If allowed to remain, rim rust will eventually eat its way into the metal, leaving pits and weakening the structure of your rims. Rust should be removed from <a href="/car-repair/understanding-your-tire-sidewall-markings">tire</a> rims as soon as it is noticed in order to prevent permanent damage. Rust removal can be performed on steel and true chrome rims. Tire rims that have been painted with chrome paint will be scratched with the following process, and should not be used.</p>
<h3>Tools and Materials Needed</h3>
<ul><li>Mild soap and water mixture</li>
<li>Stiff bristled brush</li>
<li>Clean, lint-free towels</li>
<li>Rubbing alcohol</li>
<li>Wire brush and steel wool (Medium grade and Fine grade)</li>
<li>Chemical rust remover</li>
<li>Safety equipment </li>
<li>Rust proof coating (Clear sealant, Rust-Oleum paint)</li>
</ul><h3>Step 1: Clean the Tire Rims</h3>
<p>Use a mild soap and water solution and a stiff bristled brush to clean all dirt and debris from the tire rims. Once tire rims have totally dried, completely wipe them with a towel dampened with rubbing alcohol.</p>
<h3>Step 2: Tire Rim Rust Removal</h3>
<p>Using the wire brush and/or the steel wool (medium grade), brush and rub the affected area. The amount of force you will need is dependent on the severity of the rim rust. Periodically wipe the area off to check on your progress. Remember, you do not want to be too aggressive and damage the underlying metal. Use the chemical rust remover as directed to remove more stubborn areas of rim rust. If you come across an area of deep rust, do not remove it or it will leave a pit. If you find a few small areas like this, you may want to apply a chemical to bind the rust, such as Plus Rust Converter. This product ensures that none of the metal from the tire rim is lost. The deeply rusted area will be converted to a useful metal coating that can be finished with paint and/or sealant. Note that if you found large areas of deep rust or have found many areas of deep rust, you should consider scrapping the tire rim and getting a new one. Finally, use the fine grade steel wool to buff and polish the previously rusted areas.</p>
<h3>Step 3: Applying Protective Coating to the Tire Rims</h3>
<p>After the rim rust has been removed, and the areas have been buffed and polished, wipe down the tire rims with an alcohol dampened cloth. This will ensure an oil and dirt free surface for the protective coating. Following the manufacturer's application instructions, spray or paint the protective coating on the tire rims. Allow the rims to fully dry. Lightly buff out the tire rim with the fine grade steel wool, and wipe clean with an alcohol-dampened towel. Once the alcohol has dried, apply a second coating of the protectant.</p>
<p>A tight budget does not mean you have to live with shabby looking tire rims. With a little bit of time and elbow grease, you can keep rim rust at bay and have nice looking tire rims on your vehicle.</p>

<p>For the beginning automotive performance enthusiast, <b>cold air intake kits</b> are a tempting proposition. Most kits are easy to install, quite affordable, and can offer substantial performance gains. especially on turbocharged vehicles, but not all kits are equal. Cool air intake and short ram intake kits vary quite a bit in their design as well as in their performance, so before purchasing a kit, there are a few important things you should know.<br /><b><br />1. Does the Intake Incorporate a Thermal barrier?</b></p>
<p>Intake systems may ingest their air from a cool, dense source, but if the intake is not protected against thermal contamination, power gains may be minimal. Construction from a material that resists heat transfer such as certain plastics or composites, such as carbon fiber, can have a huge impact on intake temperature, as can a thermal barrier coating such as those made from zirconium or ceramic.<br /><br /><b>2. Does the Intake use an Oiled Filter Element?</b></p>
<p>Oiled filter elements tend to offer decent filtration, but can pose a problem when it comes to air metering devices such as mass air flow units. During normal use, countless microscopic particles of oil can contaminate airflow meters, and over time cause failure or malfunction. For vehicles with Mass Airflow Units, sticking to an intake that uses a dry filtering element will reduce trouble down the road.<br /><br /><b>3. Is the Intake CARB approved?</b></p>
<p>For those living in California, California Air Resource Board approval, or a CARB exemption order is an important aspect to look into. Any modification to the intake or exhaust system of a vehicle operated on public roads must be approved and certified to not inhibit or affect the emissions controls of the vehicle. What this means simply, is that in California, an intake system must have a CARB EO number, or you may be fined or have your car impounded.<br /><br /><b>4. Is Water Ingestion a Concern?</b></p>
<p>In areas with regular rainfall,&nbsp; cold air intakes that draw their air from the fender well or the bottom part of the bumper may be at risk of ingestion water should the vehicle be driven through water more than a few inches deep. Companies such as AEM offer a bypass valve to prevent ingestion of water on their cold air intakes, while others may use a two piece design that allows conversion to a short ram intake by removing the lower portion in order to prevent water ingestion. If the intake does not include one of these features, and you live in an area with heavy rainfall, you may need to be especially careful, or you may face extensive engine damage.<br /><br />Cold air intakes offer a lot of advantages, but like any modification, care must be taken when choosing the product or engine damage may result. Cold air intakes are a very common modification offered by a variety of companies and as such, many are designed with profit in mind rather than safe, reliable performance. By checking the above four points against the intake in question, you can greatly reduce the chances of problems in the future.</p>]]></content></entry><entry ><title>Advantages and Disadvantages of a Glasspack Muffler</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/advantages-and-disadvantages-of-a-glasspack-muffler"/><id>142109</id><published>2010-06-15T19:41:35Z</published><updated>2012-10-31T19:43:33Z</updated><summary><![CDATA[

<p>A good <b>Glasspack muffler</b> is one of the best mufflers present in the automotive world nowadays. The design is simple. The exhaust passes through the center of the pipe and the padding around the exhaust pipe muffles the vibration and sound of the engine. But this variety of muffler does have its advantages and disadvantages too.</p>
<p><b>Advantages of Glasspack Mufflers </b></p>
<p>Glass pack mufflers work on the simple principle that all the sound generated by the car engine is passed through a sound absorbing material before it is released. This means very little sound is allowed to escape the muffler, and the sound blanketing capacity of the muffler is excellent. Several people commonly refer to the Glasspack Muffler as the Cherry Bomb Muffler due to its really great sound muffling abilities. These mufflers are also much better than ordinary mufflers, as they do not allow the sound to resonate back into the engine. This usually happens in ordinary engines, causing them to dissipate without damaging human ears. The loud sound of the engine is negated by the same loud sound produced by an ordinary muffler. But this creates negative pressure on the engine. The glasspack muffler reduces the pressure on the engine by dissipating the pressure of the loud sound waves out through a sleeve of glass particles. Another advantage is that they are quite cheap at about $20-$100.</p>
<p><b>Disadvantages of Glasspack Mufflers </b></p>
<p>Glasspack Mufflers don't really work on every kind of car. Another problem is that as they do get old, they start to sound really bad. They require regular care too.</p>
<p>But on the whole Glasspack Mufflers are pretty good. They offer value for money and have a good capability for absorbing sound. But make sure you check with the garage before you get them installed.</p>]]></content></entry><entry ><title>Performance Muffler Tips: Getting Rid of Raspy Sound</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/performance-muffler-tips-getting-rid-of-raspy-sound"/><id>142114</id><published>2010-06-15T19:41:47Z</published><updated>2012-10-31T19:42:58Z</updated><summary><![CDATA[

<p>The popularity of <b>airbag suspension </b>kits among automotive enthusiasts created awareness on the benefits of installing such a system on your car or truck. While it may be identified among custom low rider trucks as seen on car shows, airbag suspension presents numerous benefits to the car and truck owner that somehow equals the stiff price tag for parts and labor. Purists swear in the improvement of overall road handling and ride comfort offered by these revolutionary suspension kits. Depending on the type of system installed, a custom airbag suspension could inflate and deflate automatically, or at the owner's behest to accommodate heavy loads or adjust to specific terrain. But before deciding to make the important purchase, here are four things you need to know about buying an airbag suspension for your vehicle:</p>
<h4>1. Cost</h4>
<p>It is no secret that such&nbsp;a technological triumph would cost an arm and a leg but&nbsp;due to the increase in makes and models available, a proper airbag suspension system could be yours for&nbsp;below $300 exclusive of labor. Take into consideration the fact that all your&nbsp;stock suspension components would be replaced by this system, including heavy springs and shock absorbers. There are a lot of airbag suspension kits available in&nbsp;the online market that will cater to any basic whim or automotive desire, and proper research should be&nbsp;made&nbsp;to make the most of this rather expensive purchase.&nbsp;</p>
<h4>2. Needs</h4>
<p>Since the modification will affect overall vehicle appearance and performance, properly determine your needs for purchasing an airbag suspension system before making the decision of ordering or buying. There are a lot of air suspension kits in the market and most are designed for a specific role. There are kits for serious off roaders and are more expensive than those for street or normal use. Intermediate air suspension systems are OEM designed to improve ride comfort while having the ability to adjust ride height. There are air suspension kits for competition purposes and are popular among the racing and custom car industry. Properly determine the kind of air suspension system for your specific vehicle.</p>
<h4>3. Installation</h4>
<p>Due to the complexity of various wiring and hose installations, fitment of an air suspension system should be left to a professional and knowledgeable mechanic. There are DIY kits available for the mechanically inclined consumer, but as the installation of an air suspension requires the use of various tools, the newbie is best left with the option of hiring a mechanic. Remember that vehicle integrity and safety is at stake and proper installation will assure that such objectives are readily met. Take into account that most kits require professional installation for the warranty to be honored, and a sub par installation will void such a&nbsp;warranty.</p>
<h4>4. Maintenance</h4>
<p>Air suspension kits manufactured by reputable companies are durable and exhibit major performance upgrades for any motor vehicle application, but as such parts are exposed to harsh road conditions, wear and tear could never be ignored and is a fact worth considering. Yes, air suspension is lighter and many times more durable than stock vehicle suspension components, but proper maintenance should be undertaken according to manufacturers specifications.</p>
<p>Air suspension should not be confused with hydro suspension systems (hydraulics)&nbsp;as form and function&nbsp;differs greatly between both&nbsp;applications. But cost considerations aside, an air suspension is a wise investment for those who&nbsp;desire the best&nbsp;in terms of performance.&nbsp;</p>]]></content></entry><entry ><title>The Benefits and Drawbacks of Twin Turbos</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/the-benefits-and-drawbacks-of-twin-turbos"/><id>145490</id><published>2010-06-28T18:40:18Z</published><updated>2012-10-31T19:38:19Z</updated><summary><![CDATA[In the mid to late nineties, twin turbos were the feature to have on many flagship performance vehicles from Japan.

These vehicles boasted large amounts of power, superb acceleration, and extensive potential for tuning. Though, as time has passed, both the benefits and advantages of the twin turbo layout have become quite apparent. <br /><br /><b>Parallel Twin Turbochargers</b></p>
<p>Parallel mounted twin turbochargers are used on a variety of upscale performance and luxury cars alike. This design, most commonly found on V type engines, uses a turbo for each bank of cylinders, with both running full time. The purpose of this layout is to reduce the amount of piping required for the plumbing of the intake and exhaust systems, which can increase response and reduce turbo lag. To this end, parallel twin turbochargers also tend to be smaller than what you would typically find on a single turbo engine of similar displacement. Because there is less exhaust gas available to each turbo, a smaller turbo must be used to maintain quick response, and the cost for this response, is limited high end power delivery and boost potential. For those seeking power, this can be the parallel twin turbocharger's greatest weakness next to cost. <br /><br /><b>Twin Sequential Turbocharger</b></p>
<p>A sequential twin turbocharged layout generally uses a paired combination of a small turbocharger for low end response, and a larger turbocharger for high rpm power. To avoid lag problems, the smaller turbocharger maintains quick response at lower engine speeds and also helps to spool the larger turbocharger via the increased exhaust flow. At higher rpm or at a factory determined switch over point, the workload is shifted to the larger, secondary turbo, allowing for high boost without the presence of the lag that would be apparent with a single large turbocharger. While sequential turbochargers help bridge the gap between top end power and low end agility, they tend to be overly complex, and in the case of the Mazda RX-7 Twin turbo, can even contribute to reliability concerns. In addition, for the custom tuner, the profiles of the smaller and larger turbocharger can be quite difficult and expensive to properly match. Because of this, many enthusiasts will simply upgrade to the simplicity of a larger, single turbo.<br /><br />Twin turbo charging should not be confused with twin charging, which consists of the use of both a supercharger and turbocharger plumbed inline of one another. Twin turbo charging deals only with the use of two turbochargers, either in a sequential or parallel layout. Both of these layouts tend to suffer from large maintenance and modification costs, but besides this point, each has its own unique strengths and weaknesses. With parallel twin turbochargers, the biggest downside is likely the limited high rpm power, while sequential twin turbo setups suffer mainly from the complexity inherent of their designs. For both of these designs, single turbocharger kits are generally sold as upgrades due to their reduced complexity, higher potential power and improved reliability. For those who are willing to deal with the trouble and expenses however, a properly matched sequential turbocharger may be hard to beat.</p><div><br /></div><br /><h2>Related Questions and Answers</h2><b>What Is a Water Cooled Intercooler?</b><br /><p>A <b>water</b>-<b>cooled intercooler</b> is used in a turbocharging system to help keep the fuel-air charge as dense as possible. Often exposed to long runs of heat generated by the engine, the normal fuel-air charge doesn't remain dense for long and this impacts turbocharger performance. A water-cooled intercooler sits on the "cold" water side of the radiator system, often having its own radiator fins, and this system helps to ensure that the fuel-air charge remains cool and dense for maximum power output.</p><b>How Does an Oil Cooler System Help a Car Intercooler?</b><p>An <b>oil cooler system</b>, similar in concept to a car's engine radiator system, helps an intercooler by taking the heat away from the engine. As much as the engine's oiling system works as a lubricating system - always a key component of any engine system - the oiling system also works as a cooling system. It moves much of the heat built up by the oil to the water jacket, and then out into the car's normal cooling system. An oil cooler, (by placing cooling fins or added cooling surface at or near the intercooler,) helps to keep the air-fuel charge dense by using the oiling system to remove excess heat.</p><b>What is the Ideal Temperature for Car Air Intakes?</b><p><b>Car air intakes</b> work best when the fuel-air charge delivered to the fuel injector body is as cool and dense as possible. The best range of temperature for air-fuel charge should be in the range of 50-90 degrees Fahrenheit, as this is an almost perfect temperature to assure the best performance possible. Unfortunately, although this may be the temperature at the air intake, by the time the air-fuel charge works its way into the cylinders, it about doubles. This means that it is not dense, which is the key to engine performance.</p><b>What's the Difference Between a WasteGate and a Blow Off Valve in a Turbocharger?</b><p>A blow off <b>valve</b> on a <b>turbocharger</b> is designed to blow off or release the pressure that has built up in the intake manifold as you let off the throttle. Without a blow off valve, this pressure would end up back feeding to the turbo casing. This would cause the impeller to slow down, making getting back up to full power when you hit the throttle again slower. This is called turbo lag. The waste gate regulates the amount of boost the turbo puts into the motor. A turbo builds boost via a spinning impeller. When the PSI reaches a certain level, the waste gate opens, releasing the exhaust. When it falls back to a pre-determined level, the waste gate closes again. A simple way to remember is that a blow off valve regulates the pressure on the intake side of things, and the waste gate regulates it on the exhaust side.</p><b>Is a Supercharger Blow Off Valve the Same as a Turbocharger BOV?</b><p>Yes, a <b>supercharger blow off valve</b> is the same as a blow off valve on a turbocharger. The blow off valve vents the boost pressure between the turbo or supercharger and the intake manifold. This helps to alleviate compressor surge. This is the build up of pressure when you lift off the throttle under boost. The pressure will back up into the turbo or supercharger, which will slow the impeller, causing turbo lag. The blow off valve releases this extra pressure into the air or back into the compressor inlet depending on how it is set up. As it purges, it will make a 'pssst' noise. The blow off valve performs the same function on a supercharger and a turbo charger.</p><b>What are the Most Common Symptoms of Turbo Lag?</b><p>There is really only one main symptom of <b>turbo lag</b>, and that is the hesitation felt between the time you step on the accelerator, and when the turbocharger kicks in to boost. Turbo lag is inherently built into the system, as they are designed to operate at very specific RPM ranges. Air flow is very important to a turbo charger and how fast exhaust manifold pressure builds affect the turbo. Turbo lag will occur at different RPM levels in different cars, so no two cars will experience the same type of lag. The same can be said for correcting or minimizing lag. Each car will require a specific solution. Turbo lag can never be completely removed, but it can be reduced.</p>]]></content></entry><entry ><title>Benefits of Individual Throttle Bodies</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/benefits-of-individual-throttle-bodies"/><id>145549</id><published>2010-06-17T19:21:01Z</published><updated>2012-10-31T19:36:40Z</updated><summary><![CDATA[

<p>When it comes to naturally aspirated and turbocharged vehicles alike, it is hard to beat the response and efficiency of <b>individual throttle bodies</b>. Unfortunately because manufacturers often tend to prioritize cost over Peak power, individual throttle bodies are a rare sight in factory equipped vehicles, and generally limited only to the highest performing models such as the BMW M3 and Nissan Skyline. When cost is no object however, individual throttle bodies have several distinct advantages over their single throttle body counterparts.<br /><br /><b>Single Throttle Bodies</b></p>
<p>Most vehicles come from the factory with a single throttle body primarily due to cost concerns, as individual throttle bodies tend to be far more costly and contain far more individual parts. In a single throttle body design, air rushes into the intake manifold&rsquo;s plenum when the throttle is opened. While the response is relatively quick, there is still a brief pause between the time the air rushes into and fills the plenum, and when it actually runs into each cylinder. No matter how well tuned the engine is, or how balanced and blueprinted its components are, this lag will always be present, however miniscule. <br /><b><br />Individual Throttle Bodies</b></p>
<p>In a vehicle equipped with individual throttle bodies, the plenum if equipped, remains full of air whether the throttle is open or closed. Because of this pre-filled state, there is no wait when the throttle is opened, and air rushes directly into the engine, resulting in a crisp and responsive throttle. In some extensively modified, naturally aspirated engines, the plenum may be removed altogether, allowing room for tuned velocity stacks designed to compliment a specific power curve and make more useable power. In high horsepower engines, individual throttle bodies also tend to flow air more efficiently, freeing up power and complimenting high lift cams or high levels of boost.<br /><br /><b>Potential Concerns</b></p>
<p>Individual throttle bodies, when run without a plenum may be more susceptible to dirt and dust and excessively loud for street use. These engines should not be operated in areas of excessive dust and dirt without adequate filtration. It should be noted that for vehicles equipped with mass air flow sensors, a sealed intake system will be required for proper operation, as is the case with Nissan&rsquo;s RB26DETT engine, which is equipped with a standard plenum style intake manifold equipped with individual throttle bodies. Individual throttle body kits are generally very expensive due to the precision and machining required. Often times as much as 3-6x more than a comparable single throttle body upgrade. Because of the limited power increases they may make with an otherwise stock engine, they are often times better suited as a finishing touch rather than a starting point.<br /><br />The power your engine can generate can be limited by restrictions and inefficiencies. At stock power levels, these restrictions may not be apparent. But in a highly tuned engine, they can become severe bottle necks to airflow, and thus largely reduce power. Individual throttle bodies not only offer superior response, but they also reduce these restrictions, freeing up power through improved airflow, with little to no trade off other than cost and increased engine noise.</p>]]></content></entry><entry ><title>How to Tell if a Car Speaker is Blown</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/how-to-tell-if-a-car-speaker-is-blown"/><id>180210</id><published>2010-08-12T18:40:16Z</published><updated>2012-10-31T19:34:43Z</updated><summary><![CDATA[

<p>One of the most frustrating things that can happen to a <b>car speaker</b> is for it to blow out. Blown car speakers are very difficult to repair, and the sound quality that they produce will be greatly reduced. In many cases, you'll be able to recognize whether a speaker is blown by listening almost immediately. Tweeter car speakers and other types can also have problems with wiring, power levels and more. Each of these can result in a similar sound to the stereo system, but not actually mean that the speaker is blown. Therefore, it's important to check and be sure that the speaker is blown before you resort to buying a new one.</p>
<h4><b>Step 1 - Listen to the Speaker</b></h4>
<p>If you worry that a speaker in your car stereo system may be blown, listen to it carefully. Stop the car so that you don't have any other noises to distract you. If a speaker is completely blown, it will likely not produce any sound and may just make a soft hissing or ringing sound instead. This should be relatively easy to identify. A partially blown speaker, on the other hand, may produce somewhat normal sounds at lower volumes, but will likely become more and more distorted the louder that the system is designed to go. Therefore, you should listen to the speaker at a range of different volumes to determine if the distortion remains constant or if it seems to worsen.</p>
<h4><b>Step 2 - Check by Touch</b></h4>
<p>Many larger speakers, like woofers and subwoofers, will actually vibrate when they are actively creating sound. Turn the volume of your speaker system up and place your hand against the front padding of the speaker. If you feel any vibration, the speaker is creating sound. However, if you do not, it's likely that your larger speaker is not working properly. This test will not work as well for softer or smaller speaker sets.</p>
<h4><b>Step 3 - Isolate the Speaker in Question</b></h4>
<p>Use the fader system controls on the head unit of your car stereo to help isolate the single speaker or couple of speakers that you think may be blown. If you can focus the sound in one portion of the car, you'll be able to tell better if the speaker in question is not working properly. The sound will almost fade out or will fade out entirely when you focus the sound from that speaker.</p>
<p>If you have additional problems with a car speaker and you're unsure if it's blown out or not, disconnect the battery and examine the wiring. If the problem seems to be with a single speaker, look to make sure that speaker is still wired to the amp and the head unit properly. If you have any other questions about how to diagnose this problem or are unsure of where to proceed, take the speakers and car to an audio professional at a store in your area.</p>]]></content></entry><entry ><title>The Best Subwoofers for Cars, Trucks and SUVs</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/the-3-best-subwoofers-for-suvs"/><id>180217</id><published>2010-08-25T17:45:52Z</published><updated>2012-10-31T19:34:20Z</updated><summary><![CDATA[

<p>Determining the <b>best subwoofer</b> for your vehicle is a difficult process. In some cases, you'll be looking for subwoofer performance above all else; in others, you may be looking at subwoofer size or price.</p>

<p><b><font style="font-size: 1.05em;">Performance and Price</font></b><br>
Two of the biggest factors in the decision of which subwoofer to choose are performance and price. While it's true that the best subwoofers tend to cost more than others, you don't necessarily need to purchase the most expensive one in order to meet your needs. Analyze what kind of music you play, how often you use the sound system, how much you're investing in the other components and more. You may find that a less expensive subwoofer will completely meet your needs without breaking the budget.</p>

<p><b><font style="font-size: 1.05em;">Other Factors</font></b><br>
Size is another important determining factor. Some subwoofers are simply too big to fit into certain types of cars. Analyze where you'll place the subwoofer in the vehicle. Decide how large it can be based on that. You also want to determine how you can best enclose the subwoofer within that space.</p>

<h2><font class="Apple-style-span" style="font-size: 1.25em; ">The Best Subwoofers for Compact Cars</font></h2>

<p>While it's true that there's no single best car subwoofer for every person and car, there are some that work better for certain situations than others. A compact car subwoofer may be adequate for your needs, depending not only upon the size of your vehicle but also on your music listening preferences.</p>

<ul>
    <li><b>8" subwoofers.</b> The smallest sized subwoofers commonly available are those around 8"es across. For many larger vehicles and high end sound systems, an 8" subwoofer will not be adequate for the job. The subwoofer sound is likely to not be as pristine or as powerful as that of a larger, wider subwoofer. However, if you have a small car and a limited amount of space in which to place a subwoofer, you should consider the 8" variety. The sound will likely be adequate for what you need to fill up the space inside of your vehicle. 8" subwoofers are also easy to install, portable and less expensive than larger ones. The best 8" subwoofers are generally those made by Alpine
    <li><b>10" subwoofers.</b> The next largest is the 10" subwoofer. Many people with compact cars still find that this is a good option for them. A subwoofer that is 10 inches wide generally has much better sound quality than that of an 8" subwoofer. Another benefit to these subwoofers over the smaller ones is that there are a number of additional manufacturers, meaning that you'll have a wider selection. Top rated 10" subwoofers include those made by Pioneer
    <li><b>Pairs of subwoofers.</b> If you prefer to have an extraordinary amount of bass sound in your compact car, consider getting two subwoofers. Generally speaking, you want to purchase two of the same type of subwoofer to create an even and balanced sound throughout the vehicle. With two subwoofers, you also need to ensure that you have an amplifier set up in the car. This will direct the power to both subwoofers evenly and you with a single place to connect all of the different speakers. People who are looking to install a professional level sound system generally go for two small-sized subwoofers in their compact car. Alpine is known for producing some of the best subwoofers that work in pairs, regardless of size
</ul>

<h2><font class="Apple-style-span" style="font-size: 1.25em; ">The Best Subwoofers for Trucks</font></h2>

<p>There is a wide variety of truck subwoofers and truck car speakers out there. A truck subwoofer will give your vehicle an added dimension that you've been looking for. The bigger the subwoofer, the more bass you will get.</p>

<ul>
    <li><b>Kicker Comp 07TC104C12 Vent Truck Box 4-Ohm.</b> This model features a 10" subwoofer in a specific enclosure for better performance and power. It has 150 watts and gives maximum sound quality for your truck. The great thing about this subwoofer is that it will not take up much room if you're restricted on space
    <li><b>Kicker 07tcvt 2-2 Comp Vt series 12" 2 Ohm 800 Watt.</b> This subwoofer is a perfect choice for your truck if you want loud sounds with a huge amount of power. It features an enormous 800 watts in a 12" subwoofer, so it's still not that large if only limited space is available. Another advantage is that it comes packaged in an enclosure box that is sealed. It is also weather resistant and waterproof with its cover, and protected in case you have an accident in the truck
    <li><b>Orion XTRPRO122.</b> This pack has a 12" subwoofer along with 500 watts of power RMS rating. This is a perfect choice for trucks because it comes with an enclosure box. It doesn't take up much space and is easy to install
</ul>

<h2><font class="Apple-style-span" style="font-size: 1.25em; ">The Best Subwoofers for SUVs</font></h2>

<p>There are many SUV subwoofers to choose from and many different subwoofer sizes. If you choose the correct subwoofer for your needs, it gives you a sound that is free from distortion and you will enjoy it far more.</p>

<ul>
    <li><b>Rockford Fosgate P3D412 Punch P3 12" 500 Watt.</b> When searching for a great subwoofer, look no further than this. This includes some great bass sounds and is extremely strong and durable. You won't be able to break it, even if you try. It has a feature that allows it to be cooled down at certain times in order to prevent it getting too hot. It is definitely one of the best subwoofers on the market
    <li><b>Kenwood KFC-W3012 12".</b> This is a good option if you have a small budget. It's important that you have sound for your system that is very clear in terms of quality, and this will offer that. It has great performance and a price that is relatively cheap. It is very durable and will not let you down. This subwoofer is great value for money and still has all the qualities of a more expensive model

<p>You've just bought a massive <b>subwoofer amplifier</b> and you're going to install it yourself. You've heard of the phenomenon called a "ground loop" from the salesman, but he didn't or couldn't explain what a ground loop is or how it can adversely affect the quality of the audio reproduced by the new, high-end car audio system. In a nutshell, properly grounding amps is extremely important in order to obtain noise-free audio.</p>

<p><b><font style="font-size: 1.05em;">Ground Loops Explained</font></b><br>
A ground loop is an electrical fault that occurs when two pieces of equipment in the same system are not at the same ground potential. If your car stereo head unit is grounded directly to the battery and your subwoofer amplifier is grounded to a sturdy piece of metal in the trunk, they will most likely, due to the inherent resistance in any type of electrical conductor such as the car's body/frame, be at different ground potentials. The ground loop will make itself known by a hiss or hum heard in the audio reproduced by the stereo system.</p>

<p><b><font style="font-size: 1.05em;">How to Defeat a Ground Loop</font></b><br>
All 12-volt components need to be grounded at the same location. This is something to consider when performing a subwoofer installation. The best way to ground your car stereo components is to run a 10 or 12-gauge wire from the amp, and 12-gauge from all other components, such as head unit and active crossovers, to a central location. Then run a single ground to the best source of ground, the negative terminal on your car's battery. What many professionals do is run everything to a circuit strip and then run a single wire to the battery to supply ground for everything. Other good places to obtain a single ground connection are:</p>

<ul>
    <li>Dashboard electronics ground point under the dash, usually by the brake pedal
    <li>The tail and brake lights grounding point in the trunk
</ul>

<p>Be sure to remove any paint from the point you choose to use as your single grounding point.A properly grounded subwoofer amplifier will deliver clean, noise free low frequency audio for years.</p>

<h2><font class="Apple-style-span" style="font-size: 1.25em; ">3 Reasons Why Subwoofer Amps Overheat</font></h2>

<p>Without an amp to help regulate them, a subwoofer set may not work properly. The amp helps to regulate the power that flows to the subwoofers. If you don't have an amp system set up, the subwoofers will be on their own and may run into problems. If the amp wiring isn't set up correctly or if there are other problems, you may have to deal with your amp overheating. This in itself can cause a number of issues.</p>

<p><b><font style="font-size: 1.05em;">Improper Amp Wiring</font></b><br>
One of the most common issues that can cause the amp and or the subwoofer to overheat is if the wiring isn't set up correctly. The best way to be sure that your amp is set up properly is to check on the wiring with a professional's help. Have a car stereo expert look into the system after you've installed it, to give the okay as to whether or not the amp wiring is set up properly.</p>

<p>Generally speaking, it isn't that difficult to install and wire an amp in your car. There are a number of good guides for doing so online, and you can also find a set of instructions for basic setup procedures in most amp installation kits that come with the components. Being sure that you take the extra time to wire the amp with the appropriate wire and to the right channels can save you time and money later on.</p>

<p><b><font style="font-size: 1.05em;">Incompatibility between Components</font></b><br>
In certain cases, if your amp isn't compatible with your head unit, or if the subwoofers aren't compatible with the amp, you may run into overheating problems. This could be because of a discrepancy in the Ohm rating of the different components, which results in a conversion of voltage that can overheat the amp and cause it to break down. Be sure that the power ratings for each of these components are the same throughout the entire car audio system.</p>

<p><b><font style="font-size: 1.05em;">Overuse</font></b><br>
You may have overheating problems in your amp simply from overusing it. If this is the case, you may consider temporarily shutting off the audio system or, if you wish, removing the amp from the circuit and connecting the subwoofer directly to the head unit for a short period of time. You can also turn off the subwoofer completely and power the stereo only through the other speakers in the car, although this may distort the sound.</p>

<p>If your amp is overheating, shut it off right away to avoid further damage, including fires and other potentially harmful effects. Ask a professional car audio expert for additional advice as to what you can do to remedy this problem.</p>]]></content></entry><entry ><title>Wheels and Rims: How to Prevent Tire Rub</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/wheels-and-rims-how-to-prevent-tire-rub"/><id>184281</id><published>2010-09-03T18:40:03Z</published><updated>2012-10-31T19:33:33Z</updated><summary><![CDATA[

<p>Your vehicle's <b>wheels and rims</b> need to be matched so that their combined size does not extend past the wheel well clearances. Both tire rub and bent rims can be caused by not leaving enough clearance in the wheel wells. Without clearance, the wheels will be thrust into the wheel well whenever you hit road bumps.</p>
<p>When you select larger wheels and rims, you have to take into account the sidewall height and width of the tire used. In addition, the larger rim must still be able to handle the weight of the vehicle. Before running out and purchasing the wheels and rims of your dreams, you need to invest some time and gather clearance information about your vehicle. Without this information, you could experience both tire rub and bent rims. Tire rub will destroy your expensive tires, and driving on bent rims is unsafe. Not only that, but once you bend a rim, it is useless and must be replaced.</p>
<p>Before you go to the tire center, inspect the sidewall of your tire and look for the tire size information that is molded into it. The first number indicates how wide the tire is. This number is in millimeters. It may be preceded by a letter such as "P" or "LT". The "P" indicates a passenger classification for that tire, and the "LT" indicates that the tire should be used on a light truck. The next number, after the slash, is a percentage. That number is multiplied by the tire width to obtain the sidewall height. If there is not a number in that position, then it is assumed to be 80 percent. The last number, following the "R," is the tire (and rim) diameter in inches. The distance from the center of the axle to the top of the tire is the combined height of the wheel and tire. By knowing the combined height and the wheel well clearance measurements, you can avoid tire rub and bent rims.</p>
<p>Make your measurements with the vehicle on a flat, level surface, and at its normal load (that means no storage in the vehicle). Pick a side to start on and repeat the procedure for the other side once all of the measurements have been recorded. Measure the combined height of the wheels and rims. This number will be the same, with almost no variance, for both sides. With wheels aiming straight, measure the clearance between the top of the tire and the wheel well. Next, measure from the front and then the back of the tire to the wheel well. Turn the wheel all the way to one side, and measure between the tire and wheel well at the closest point. Repeat this same measurement after turning the wheel fully in the opposite direction.</p>
<p>Select wheels and rims that have a combined height that will fall within the clearance measurements, and you can avoid tire rub and bent rims. Remember, if your vehicle has very little clearance space, then select wheels and rims where the combined height is the same as the ones you are replacing.</p>]]></content></entry><entry ><title>Advantages and Disadvantages of a K&amp;N Air Intake System</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/advantages-and-disadvantages-of-a-kn-air-intake-system"/><id>142102</id><published>2010-06-15T19:41:26Z</published><updated>2012-07-02T22:35:56Z</updated><summary><![CDATA[For those in the market for an air intake system, a K&amp;N air intake system is often recommended, and rightly so.

A popular choice not just because of K&amp;N&rsquo;s extensive history and great reputation, K&amp;N intake systems offer proven performance gains for minimal cost and installation effort. Like any product however, these are not without their downsides. To understand the full picture when it comes to the K&amp;N intake, a break down of the product&lsquo;s advantages and disadvantages can be especially helpful in understanding exactly what you are buying.<br /><br /><strong>Advantages of Buying K&amp;N</strong></p>
<p>K&amp;N products will not void your vehicle&rsquo;s warranty and, in some cases, sold by the dealership. Which means you can increase your vehicle&rsquo;s performance without worrying about problems later on. K&amp;N intakes use a reusable filter which reduces costs down the road, and allows the owner to clean and re-oil the filter, as environmental conditions warrant by using a reasonably priced filter oil kit and cleaning products. While many intake kits will draw their air from the inner fender well or lower portion of the bumper, most K&amp;N filters choose a safer location and use a supplied heat shield to help keep out hot engine bay air. While this may result in slightly lower power increases, it also means that should rainy or wet weather surprise you, you can continue driving without worrying about water ingestion, and the severe engine damage that results from it.<br /><br />K&amp;N air filters are covered by a million mile warranty, which means you will only ever need to purchase a single filter, while many other brands will have you purchasing new elements every 1 to 2 years or more. <br /><br /><strong>Disadvantages of Buying K&amp;N</strong></p>
<p>As mentioned above, the location of the filter in most K&amp;N intake systems tends to be in a position that is safer and less likely to ingest water. While this greatly improves reliability, for those living in extensively dry climates, a traditional cold air intake may provide moderately higher power increases on some vehicles. Because K&amp;N filters use an oiled filtering element, there may be long term problems in vehicles equipped with mass air flow sensors, as oil can build up over time and cause fouling or errors in the sensor which require cleaning. While none of these are especially large concerns, one problem for those living in California, is that K&amp;N intake systems are not CARB exempt, meaning they are not legal for use on public roads. It should be noted that this only applies to K&amp;N&rsquo;s air intake systems, and not the filter itself, which does not violate any of California&rsquo;s strict emissions laws.<br /><br />There are very few reasons not to buy a K&amp;N intake system, as with K&amp;N products, you always know what you are getting. Power gains are proven and displayed for each individual application, and their products are backed by extensive warranties. If you are unsure about which intake system is the best choice for your vehicle, K&amp;N is a safe bet, and one that will not cause any warranty concerns down the road.</p>]]></content></entry><entry ><title>Vehicle Suspension Types: Coilovers vs Springs</title><link  rel="alternate" type="text/html" href="//www.carsdirect.com/aftermarket-parts/coil-spring-suspension-vs-leaf-spring-suspension"/><id>164074</id><published>2010-07-27T18:40:29Z</published><updated>2012-04-06T19:15:12Z</updated><summary><![CDATA[The debate over coilovers vs springs regarding suspension systems generally leans in favor of coilovers.

The coilover suspension is something that has a lot of do-it-yourself auto customizers talking. This innovative system, available as an aftermarket addition, came from the race track to the common car population over time, and now the average driver can enjoy more of the engineering that makes race cars so cool. Specifically, the coilover allows for an enhanced suspension system by offering a single piece, made of a spring wrapped around a shock absorber that helps with what's called "damping" or absorbing impact on the road.</p>
<p>Here are some of the commonly reported good and bad points of having a coilover on your vehicle.</p>
<h3><strong><span>Advantages of a Coilover Suspension</span></strong></h3>
<ul><li><strong>Good handling. </strong>Some enthusiasts point to improved handling with coilovers as opposed to some of the stock suspension systems that come from the factory. Setting up a custom suspension can help that system do more of the work in cornering and other parts of the drive.</li>
<li><strong>Adjustability. </strong>Drivers love that these custom suspensions are adjustable. That's great for anyone who wants a "low ride" for their car. On the other hand, for off-road coilovers, a high setting will often be preferable. Being able to set your suspension any way you want to is a huge plus for these kinds of systems.</li>
<li><strong>Prestige.</strong> Telling your auto-buff friends that you installed a coilover suspension will probably get you some points. The better kinds of coilovers are well regarded in the car community as useful custom aftermarket parts, and some of the best cars around run on these kinds of specialized setups.</li>
</ul><h3><strong><span>Cons of a Coilover Suspension</span></strong></h3>
<ul><li><strong>Stiff ride. </strong>Some drivers report that coilovers lead to a stiff, uncomfortable ride. In some cases, this is because poor quality coilovers were not able to be configured correctly. Buying cheaper coilovers can really compromise ride quality and even safety, so experts recommend springing for a set with a good reputation.</li>
<li><strong>Possible failure. </strong>As mentioned, cheap and poorly made coilovers can be a real liability on the road. Some "sleeve type" designs can fail in certain kinds of driving. Read up on various kinds of coilovers before buying, to make sure they're not getting into a situation involving added risk on the road.</li>
<li><strong>Space hogging setups.</strong> There's only so much room under the frame of your car, and for some drivers, coilovers tend to eat up more than their share. Coilovers can come into contact with parts like a sway bar, tangle up wires and cables for systems like antilock brakes, or even end up in contact with tires, chewing off the sidewall. These are serious issues, and you should look carefully at your particular wheel area before trying to fit another item into your car.</li>
</ul><h3><strong><span>Leaf Springs</span></strong></h3>
<p>Leaf spring suspension is a simpler system because the vehicle's axle suspends the spring. This makes it sturdier, with higher load bearing limits. It also comes in useful when jacking a car or truck up because the leaf springs respond better to being lifted. They are also less expensive. There are downsides to a leaf spring suspension. They are less adjustable and having fixed points around the chassis of the vehicle offers far less movement, making them slightly more bumpy.</p>

Although choice is a very personal thing, there are some brands that truly stand out.</p>
<ul><li><strong>Becker. </strong>Not as well known as other brands, Becker is one of the top car stereo brands, most famous for its CD changers, which have been exceptionally well received.</li>
<li><strong>Blaupunkt. </strong>Blaupunkt is a German company that's been around since 1970 and provides car stereo systems to many high end makes. Their models tend to be named after cities, and they generally score highly when people look for the top-rated audio system.</li>
<li><strong>Clarion. </strong>Although a newcomer, at least compared to the other brands, Clarion has established itself among the top car stereo brands. Although all the models have been favorably reviewed, one standout for Clarion is its digital audio system for cars.</li>
<li><strong>JVC. </strong>JVC has a reputation both in home audio and also as one of the top car stereo brands. Based in Japan, the company has established a reputation for high quality equipment even if it's not one of the biggest brands. Its products offer extremely good value for money.</li>
<li><strong>Kenwood.</strong> Kenwood covers the whole range of car entertainment. That means not just car stereo, but also multimedia units that offer DVD and GPS, as well as speakers. They cover the entire gamut of car entertainment. Particularly popular are Kenwood CD changers.</li>
<li><strong>Sony.</strong> Sony is one of the very top and most visible car stereo brands. It's always at the cutting edge of technology and coming out with new products that score well on consumer reviews.</li>
</ul><h2 id="Blaupunkt_Car_Stereos"><span>Blaupunkt Car Stereo Speakers and Receivers</span></h2>
<p>A Blaupunkt car stereo is made by Bose in Germany. The stereo equipment is quite sleek and all of the controls are fun, though not necessarily logical. It may be necessary to search through the manual to find all the control functions. The speakers can easily handle all different frequencies, though the front speakers tend to lack in the bass department. The mid and high tones are very natural and make for excellent listening.</p>
<h3><strong><span>Bose Factory Brand</span></strong></h3>
<p>Factory brands tend to be much higher quality stereo systems than manufacturer or aftermarket systems. However, along with the better quality they tend to be much more expensive. If you want top of the line, Blaupunkt is an excellent stereo manufacturer. This brand does not cut corners or sacrifice quality.</p>
<h3><strong><span>High Quality</span></strong></h3>
<p>High quality is necessary because the acoustics of a car are not even close to ideal. It is rare for the speakers to actually face the passengers and most of the components are shrunken to fit into the dashboard. Sound reflects off of the different panels and interior and it is very difficult to predict how this works. There are also issues with external sound. High quality stereo components ensure that the best audio possible will come from your speakers. Having a subwoofer and amplifier that matches the speakers is very important. By purchasing a complete Blaupunkt stereo you can be sure that each component works perfectly with the rest of the stereo.</p>
<h3><strong><span>Installation</span></strong></h3>
<p>When purchasing such a top end stereo it is best to have it installed by a recognized installer. Make sure that you know the individual that is installing the stereo into the car, should any problems occur in the future. Additionally ensure that the fitter has all of the tools necessary to fit the Blaupunkt stereos. Most factory brand stereos have special wire harnessing, adapters and fittings in order to work in your vehicle.</p>
<h3><strong><span>The Look and Buttons</span></strong></h3>
<p>The look of the Blaupunkt stereo is quite sleek with a slick finish. This is perfect for those individuals that like plenty of buttons. It can take a little while to get used to the buttons and functions of them, as they are not necessarily all logical. There is a great fade in function when a cassette or CD is inserted. This prevents a very strong and jarring sound increase depending on the audio. The only main issue is at very high volumes, the clarity does decrease. Blaupunkt offers several different stereo systems. All are top of the line and offer the best audio experience for the car.</p>

<h3><strong>Who Makes Car Stereo Receivers with the Most Functions?</strong></h3>
<p>Although it is a toss-up, you will find that Bose probably makes <strong>car stereo receivers</strong> with the most features. They are made to work not only with a specially designed set of speakers/filters, but with specialized amplifier circuits that interface with the speaker/filters for the great sound the system delivers. Remember that Bose designs its systems around the cars they are building them for, so it takes a lot of electronic work and interface to make this system operate correctly. The runner-up (some could argue is the leader), is Sony, which makes a variety of complicated systems for vehicles. Then there's the specialized audio versions offered by Mercury.</p>
<h3><strong>Can You Add an MP3 Input to a Car Stereo, or Only Get a Car Stereo with the Input Built in Already?</strong></h3>
<p>Yes, you can&nbsp;add a <strong>car stereo MP3 input</strong> to a car stereo. An MP3 input is nothing more than a standard three-way car stereo input jack. In other words, if you were to look at an MP3 input, you would see the long outer shaft is for ground, the second or middle shaft is for one set of speakers, and the first shaft is for the other set of speakers. For some reason, once it was reintroduced some years ago as an MP3 player, the name stuck. Although it is nothing more than a standard stereo input device.</p>

]]></summary><author><name/><uri/></author><category term=""/><content type="html" lang="en-us" base="http://www.carsdirect.com"><![CDATA[<p>There are pros and cons to <strong>lowered suspension</strong> systems. Some drivers change their suspension systems so that the vehicle sits lower to the ground. Any kind of aftermarket suspension system or alteration has its own specific effects on a vehicle.</p>
<p></p>
<h2 id="Lowered_Suspension_Advantages">The Advantages of Lowered Suspension</h2>
<p></p>
<ul><li><strong>Better aerodynamics.</strong> With a lowered suspension, there's less air going underneath the vehicle, and this can create a better outcome for wind drag on a car. That's why some sportier models sit a bit lower to the ground.</li>
<li><strong>Improved traction and handling.</strong> In general, having the vehicle so low to the ground can increase the grip of the tires on the roadway and improve handling. However, this is not always the case, as lowering can in some instances cost handling issues.</li>
<li><strong>Reduced rollover risk.</strong> When its center of gravity makes it a rollover risk, almost any vehicle benefits from lowering. The higher the vehicle sits, the easier it tips over.</li>
<li><strong>Greater comfort.</strong>Some drivers report that they feel better with a lower suspension. Additional stiffness can be desired in a suspension, and this is one of the perks that some drivers mention after lowering their suspensions.<strong><span></span></strong></li>
</ul><p></p>
<h2 id="Lowered_Suspension_Disadvantages">The Disadvantages of Lowered Suspension</h2>
<p></p>
<ul><li><strong>Increased bottoming out.</strong> One of the most common problems with lowered suspensions is that the vehicle can more easily hit the road when it bounces. Speed bumps can also be problematic. Contact with the ground can cause parts of the underside of the car to be seriously damaged. The oil pan and exhaust system are particularly vulnerable.</li>
<li><strong>Uneven tire wear.</strong> In some cases, a lower suspension can cause tires to wear unevenly, or cause extreme wear patterns. Drivers should look out for this consequence when altering their suspension in any way.</li>
<li><strong>Potential conflict with other parts.</strong> An even more dangerous consequence of a lowered suspension occurs when elements of the suspension system come into contact with other vehicle systems. Low suspensions can get caught up in anti-lock brake apparatus, sway bars, or even with the sidewalls of the tires. An incorrectly set up suspension can actually chew on tires, causing some serious potential risks.</li>
<li><strong>Lifting and towing problems.</strong>For those who like to use manual jacks to raise a vehicle for routine maintenance, lowering the suspension can make a simple job a lot harder. Think about your access needs before shifting your car's frame lower toward the ground.</li>
</ul><p>All of these are important considerations for vehicle owners who want to mess around with the suspension system that came direct from the factory. Experts recommend paying extra for quality shock absorbers and other parts, and avoiding cheap aftermarket systems that can cause failure or other serious risks on the road</p>
<h2 id="Lowering_Suspension_Kits">Lowering Suspension Kits</h2>
<p>When it comes to modifying a vehicle, lowering suspension and ride height is often the first step many enthusiasts make.</p>
<p>For the best compromise between handling and looks, choose a kit that includes matched springs and shocks from the same manufacturer, with drops of no more than half an inch to an inch. This allows the spring rates to be increased with improved damping rates to match. Kits that include only lowering springs are cheap, but will generally have spring rates close to factory rates in order to be compatible with the factory shocks. What this means is that your suspension is lowered and travel is reduced, yet there is no increased spring rate or damping force to prevent bottoming out of the shocks. In the case of a rally suspension or suspension that will be used on rough, uneven roads, lowering should be avoided at all costs with attention paid to increased damping and spring rates. Lowered suspensions tend to work best on smooth roads, while excessively rough roads and uneven surfaces require near-stock ride height to function properly.<strong><span></span></strong></p>
<p><strong><span>Coilovers</span></strong><br> For the proper mix of lowering, suspension travel and damping, it is hard to pass up a full coilover kit. While these kits, such as the Tein type-Flex kit, run about $800 to $1200. Kits generally include shorter shocks and adjustable spring perches, which allow changes to ride height as situation dictates, without reducing valuable suspension travel. In addition, many of these kits are fitted with matched shocks that feature adjustable damping levels. This allows a reduced ride height while avoiding many of the problems that come with it.</p>
<p>Lowering kits from well known companies such as Eibach and Tokico are cheap and cost effective, while entry level coilover kits from companies such as Tein up the field in every respect at the cost of higher prices. For the cheapest combination, pairing Eibach Race springs with a cheap, adjustable shock such as the Tokico Illunima can allow you the choice of both spring height and spring rate in 25lb/in increments, without leaving behind changes in damping force. These available choices can help you fine tune your vehicle to perfection for the cheapest possible price.<strong><span></span></strong></p>
<p><strong><span>End Links</span></strong><br> The end links for the lowered suspension keeps several of the other components in place by securing the ends of the suspension frame parts. These links are crucial to the continued stability of the suspension kit and are available at most auto body repair shops.<strong><span></span></strong></p>
<p><strong><span>Tie Bar</span></strong><br> The tie bar extends across the base of the vehicle to secure several of the suspension parts in place as well.<strong><span></span></strong></p>
<p><strong><span>Shocks</span></strong><br> The single most important part of a lowered suspension kit is the shocks. Shock absorbers respond to the different terrain and driving styles to provide a smooth ride and to help prevent you from bottoming out.</p>
