Suspension and Your Ride

KYB Strut-Plus AssemblyThe last time you drove over railroad tracks, how well did your car respond? If it felt like your dampers were shot, it might be time to have your suspension components switched out. Or maybe your dampers aren't shot, but you'd like to change the way your car rides. Tire Rack offers a competitive selection of suspension components tailored to your vehicle's needs.

I personally found this out the hard way. While taking my wife's car, a 2004 Pontiac Grand Am, to get the oil changed, I noticed that the vehicle had a "bouncy" feel to it. The handling was very unpredictable and I could feel every imperfection in the road. 

In looking at damper options, we had our local mechanic install KYB struts in the front and rear of the vehicle. What a difference this made in the way the vehicle rides! One quick tip: always try and change out both the mounts and boots when replacing suspension components. Nothing like new products being held to your car by worn-out mounts!

For those looking to increase their vehicle's performance, consider the options available from H&R. They offer some of the best suspension components for improving handling and performance for many vehicles, including the 09 VW Jetta TDI. In addition to struts, take your suspension upgrade to another level with the H&R Coil-Over Premium Performance Kit. And to gain a better understanding on improving your vehicle's performance, read "Minimizing & Controlling Bounce."

After you've purchased suspension components and had them installed, don't forget to fill out our Suspension Component Survey. This will provide others with reviews and help them select the proper suspension products for their vehicle.

The Griot's Garage Experiment #1: Eliminating Brake Dust

Tuesday, August 23, 2011 by Spencer Diaz
There are tons of car care products out there, so how do you know which ones to choose? Reading reviews are a great start, but viewing a demonstration allows you to actually see the results. Tire Rack carries an exceptional line of car care products from Griot's Garage and through the following experiment of cleaning the tires and wheels on a 2003 Pontiac Bonneville, I'm going to show you which products I used and how I removed the brake dust: 
The culprit comes in the form of brake dust, coated stock alloy wheels. With the face and drum of the wheel quite dirty, the challenge is to clean them without removing the wheels from the vehicle. Notice the brake dust present in this before shot of the wheel. 
  
Many people, myself included, simply do not have the time to jack up their car, remove the lugs, take the tires and wheels off, clean and then torque the wheels back on. That being said, a nice tip is to use this process of cleaning if you rotate your own tires. Since you already have to remove the tires, it makes it an easy and convenient time to clean the wheels. In fact, it would also be a great time to use Griot's Under-Carriage Spray to keep the inside wheel wells looking fantastic!
 
The Multi-Pattern Hoze Nozzle and Car Wash Dispenser is not a necessity, but with 10 spray patterns to choose from it can instantly be a great car wash tool and make a nice addition to your car wash collection. I will start by spraying the wheels with the Wheel Cleaner, but only on half so you can see the side-by-side comparison. The wheel cleaner creates a reaction with the brake dust and gunk that has been left on the wheel. After a little time, you will notice that the spray has taken a purple-ish tinge and is ready to be scrubbed. 
 
Using the Long Reach Wheel Scrubbing Brush, I am able to gently remove the caked-on residue from the face of the wheel. It is an excellent tool for covering a lot of area, as well as thinner spokes.
 
The design of the brush makes it very easy to use and with a simple spray of water it washes back to clean as new.
  
The major advantage with the brush is its ability to scrub the inside drum of the wheel without it being removed from the car. The long reach of the brush makes it easy to scrub out the residue that corrodes the insides of the drums after the wheel cleaner breaks it up. I use the 3-Finger Detail Mitt to get into the crevices and harder to clean areas, like lug hole openings. It's a nice item to have to clean out the smaller areas properly with the finger coverings. After this, I use the Tire Scrubbing Brush to remove any residue from the tires themselves.    

Notice the difference in this side-by-side comparison. The left side was cleaned with Griot's products, while the right side was left uncleaned.

Side-by-Side ComparisonNow that the wheels are clean, it may also be a good time, if possible, to utilize the Multi-Pattern Hoze Nozzle and Car Wash Dispenser, and its ability to house any type of wash you would like within the added cartridge. You can use any car wash or tire wash you would like at this point along with the tire brush. I would recommend using the Long Lasting Tire Dressing as well. Not only will it protect your tires without drying them out (like many other products do), but you have the choice of getting the kind of look you desire. Like the normal look?  Add a single coat and enjoy. Like the wet sheen look? Add multiple coats.
 
All in all, the end result is a set of tires and wheels that are quick and easy to clean, without removing them from the vehicle! It is a great time saving option for the busy worker who likes to keep sections of his or her car clean!

Heir Apparent: Bridgestone Potenza RE970AS Pole Position

Wednesday, July 20, 2011 by Spencer Diaz
For years, the Ultra High Performance All-Season category has had numerous models that have ranked as some of the best tires on the market. One of these selections, the Bridgestone Potenza RE960AS Pole Position, dominated the category for years. However, with time, many manufacturers developed tires that also met the consumer’s needs in this category. In response, Bridgestone has unveiled the newest edition to their Potenza all-season lineup.

Bridgestone RE970AS Pole Position
Bridgestone RE970AS Pole Position

The Bridgestone Potenza RE970AS Pole Position is the model that will be phasing out its predecessor, the RE960AS Pole Position. While the RE960AS Pole Position excelled in handling characteristics and dry and wet traction, the RE970AS Pole Position is designed to provide additional traction in adverse conditions like snow and ice, beyond what its predecessor could accomplish. In our initial testing, we have found that the newest Ultra High Performance All-Season tire from Bridgestone compares well to the RE960AS Pole Position and holds its own against the competition's best in warm weather climates.

With an initial glance, you can see that Bridgestone maintained the utilization of a heavy directional tread design. This helps retain the outstanding wet traction that the RE960AS Pole Position was known for. Along with this, Bridgestone kept the 40,000 mile treadlife warranty. While some Ultra High Performance All-Season tires provide greater treadwear ratings, customers of the 960 and the 970 will appreciate the increased handling characteristics that the Potenza lineup has been known to offer. Building a reputation as being one of the sportiest Ultra High Performance All-Season tires on the market, the 970 looks to offer its customers a wonderful blend of handling, treadwear and overall traction.

Currently available in 24 sizes, the Bridgestone RE970AS Pole Position has been developed and released for customers with sportier coupes and sedans.

As the RE960AS Pole Position is also available in a run-flat model, Bridgestone offers many Ultra High Performance All-Season tires for your vehicle.

Upgrade to Aftermarket Wheels

Tuesday, July 19, 2011 by Spencer Diaz
Here is a common question that many people looking at aftermarket wheels ask: "Why would I want to swap them out, and will it be of any major advantage?"

The initial reason people like to modify the look of their vehicle with wheels usually starts with a desire for greater aesthetics. Original Equipment (O.E.) wheels for many applications can be cookie-cutter, and adding your own individual flair to your ride requires an upgrade. Modifying your car's appearance with a new set of wheels can give your car the desired style you are looking for.  

Adding a personal touch not only increases the look of the vehicle, but can also enhance it as well. Many, but not all, aftermarket wheels have reduced weight vs. their O.E. counterparts. The initial advantage is in unsprung weight variance. Not only can this affect the overall gas mileage of the vehicle, but also allows the vehicle to respond better, especially on imperfect roads. Lighter wheels allow for less vibrations or adverse feel to resonate in the cabin, which in turn makes for an easier and more stable ride for the passenger.

Additionally, increasing the size of the wheel not only gives the vehicle a more aggressive appearance, but can also affect the handling characteristics. In most cases, when choosing a larger wheel size, the tire size will need to be modified in order to accommodate the difference.  

As an example, a 2006 BMW 325i Sedan Base Model comes stock with 205/55R16 tires and 16x6 wheels. If one were to buy a 17" wheel, the initial choice for tire size would shift to 225/45R17. The average size of a 17" wheel for this vehicle would be 17x7.5. While the overall diameter of the tires remains about the same, the 17" size has an advantage in handling due to the tire's larger contact patch. The contact patch (a tire's "footprint") is relative to the width of the tires, and being that the width is 225 vs. 205, you have gained 20 mm in width. This will work very similar on most vehicles. As you increase the wheel size, the width of the wheel also increases. To compensate, the width of the tire increases and the sidewall gets shorter to make up for the extra inch of wheel height. The wider your tires get, the more rubber you have contacting the ground, thus increasing your handling characteristics. 

Our Upgrade Garage provides customers with the ability to view tires and wheels on their vehicle. With the example provided above, customer A would like a lightweight 18" wheel with a sporty euro design. Since the BMW 325i is a graphite color, he would like to give it a blended look. Deciding on the OZ Alleggerita HLT in the Matte Graphite Silver finish was the obvious option, giving him the clean, multi-spoke look, that will not only add aesthetics to the vehicle, but also save weight as well! Being that he wants an all-season tire that is aggressive in the snow, he chooses the Continental ExtremeContact DWS in a 225/40R18. And the customer is able to view his new wheels on his vehicle to ensure it's the look he desires! 

Note: While building a Tire & Wheel Package in the Upgrade Garage, you select wheels first and then add tires. All packages include Tire Rack's free Hunter Road Force balancing, mounting and all necessary installation hardware.

Winter Wonderland

Monday, August 9, 2010 by Spencer Diaz
Thinking about winter tires? Wondering what the difference is between a winter / snow tire and an all-season tire, and whether of not you will need them?

The first thing to understand is that it is never really too soon to be thinking about winter weather. While it may still be warm outside, fall is on its way, and with it the first shipment of winter tires comes along. Why look this early? Winter tires are usually only produced once a year, and that's it. Unlike all-season tires, or even summer tires, we will usually only receive a set amount of winter tire applications; then after that it will be another year until we get more. Not a year goes by that someone looking for a specific winter tire has to settle for something different in November because the sales volume for that tire exceeded that of our received shipment. 

Does a winter tire really work that much better than an all-season tire in wintery conditions? Plain and simple, yes. Winter conditions are a complete culmination of freezing temperatures, snow, slush and ice, usually mixed with some blend of unpleasantness that makes road conditions a possible hazard for any driver, no matter the skill. A typical all-season tire will have a rubber compound meant to be a jack-of-all-trades style and formula, thus giving the driver the ability to drive in all temperatures and all conditions, albeit not with optimum traction in each. Its design incorporates some siping (all the little lines located on the tread) that help assist with biting in slick conditions, but these are minimal as winter grip is not the all-season tire's primary concern. Dedicated winter tires, however, incorporate a rubber compound that stays soft in the most freezing conditions. That, along with an exceptional amount of siping throughout the tire, allows it to have many more biting edges than any all-season tire would. 

So, you may be asking yourself, "What kind of winter tires do I need?" That really depends on the vehicle, its size and how you choose to drive. For many vehicles, we offer a choice between Performance Winter / Snow tires, Studless Ice and Snow and maybe a few Studdable tires as well.

While studded tires are only allowed in some states, people looking for studded tire-like grip without studs will go into a Studless Ice and Snow tire. These tires promote features like squared shoulder blocks, deep tread and extra-heavy siping to give the absolute best possible grip for wintertime. They are available in low-speed rated designs as their primary concern is the best possible traction in the worst possible conditions. 

Many of the most popular Studless Ice and Snow winter tires are:These models will shift slightly for light truck and SUV applications, but will adhere to the same primary functions.

The most popular Performance Winter tires are:The difference in performance on all of these selections comes down to what you want most out of the tire itself. Each has its own emphasis, which may include traction, longevity, handling and feel, that will cause one selection to be a better choice for the way you drive than another.

Reading survey results and checking out consumer reviews will help you make these decisions and ensure that you will get the best possible fit for your vehicle.

Time for an Upgrade?

Saturday, July 10, 2010 by Spencer Diaz
Think your current ride is looking a little bland?

Need a little extra kick to make yourself stand out?

Or maybe you just want to keep your wheels cleaner?

There are many solutions to what ails your vehicle. And some of these solutions are simple fixes that will not only improve the looks, but also its performance.

Looking bland?

Start simple with some products from Griot's Garage. A simple wash can make a car look temporarily clean, but try using Griot's Paint Cleaning Clay along with their Speed Shine products to pull out the contaminants and impurities in your paint. You will be amazed at the great results you see! The paint will look and feel much smoother It will also be itching for a new coat of wax. Griot's has a great selection of different wax applications to choose from and also offers a Random Orbital Polisher to help you get professional results without damaging your paint surface.

Need a kick?

Check out our Upgrade Garage to look for great deals on Tire & Wheel Packages. Going with a new set of wheels in a stock size is a nice way to add some flair to your car without changing the ride. Adding new tires completes the process and with Tire Rack, you can be confident that it will be a perfect fit!

Already have a new set of wheels? Try lowing the car with a set of Eibach lowering springs. The lowered stance will give the car an aggressive look and help fill in that space gap between the tire and the car.

Going for a cleaner look?

Besides using the Griot's products, you can go for a brake package upgrade. Installing new, rust-resistant rotors can give the car a fresh, clean look that you will admire every time you look at your car. Add a set of new, low-dust brake pads and use some G2 Caliper Paint to finish off the process. Now your vehicle stops better than before, and you have a fresh look!

Try one of these solutions and enjoy the new sensation of falling in love with your ride all over again!
