Not everyone is looking for or needs a stiffly valved adjustable race shock. For those looking for comfort and a return of factory ride quality, an Original Equipment style replacement shock will do just fine. These shocks and struts feature a lower price tag due to a lack of adjustability and features, but aim to stop the bouncing associated with old, worn out or leaking factory pieces.
Of the shocks that fit this criteria, my favorite is the KYB GR-2/Excel-G. Featuring shock valving that is typically no more than 10% stiffer than factory, these shocks add a splash of performance without over-doing it. Add in a cost-effective price point and an industry leading warranty and you have a combo that is tough to beat.
It should be noted that the KYB GR-2 is not intended for use with aftermarket lowering springs. If you have these springs installed on your vehicle and are looking for an alternative to a KONI or Bilstein product, I suggest you check out the KYB AGX Adjustable. It features more aggressive valving and 4-8 way adjustability depending on the application.
KYB products are manufactured for a wide range of light-duty passenger vehicles including cars, trucks, SUVs, and vans. Find a KYB product that's right for your vehicle.

Coil-Over Suspension: Look Good and Stay in Control on the Street and Track
Looking for a coil-over system for your daily driver, but also want it to perform at the track? One of the most attractive features of the following options is their ride height adjustability. They feature an adjustable spring perch and a threaded shock body. You can thread the perch up and down, allowing you to customize how much lowering you prefer for each corner of the vehicle. These coil-over systems will also let you customize the tuck of the vehicle's corners.
Below are my three favorite track-ready coil-overs available at Tire Rack:
![]() Bilstein PSS10 |
![]() H&R RSS ClubSport |
![]() KW Variant 3 |
Utilizing Bilstein's shock absorbers that are designed for heat dissipation and ride control, the PSS10 Coil-Over System adds a matched performance spring and threaded ride height adjuster to provide a complete suspension system for your vehicle. The system offers ten vehicle adjustment settings and includes numbered adjusters at the base of the shock body so you know exactly what setting you are on without counting clicks.
The RSS ClubSport Coil-Over Kit is designed for the committed motorsport enthusiast who's willing to relinquish some ride comfort in return for handling performance. The firmest coil-over in the H&R street line, the RSS is the choice for weekend track and club sport events.
KW Variant 3 Coil-Overs are state-of-the-art motorsport technology for proven performance on the streets. Independently adjustable compression and rebound damping allows for custom driving set-ups. The exclusive KW patented system has dual-level valves to provide the adjustment of the rebound damping (comfort) and the compression damping in the low-speed range. High-speed settings for driving comfort are preset by KW engineers.

Initial Review, 10,000 Miles on Tires Installed on aftermarket wheels with H&R sport lowering springs and konis on a euro model. They do well in the rain and the dry performance is very good considering the long life compound used and the relatively low price up front. I think they are slightly louder than average due to the harder compound at highway speed, but I'm willing to put up with a little noise if they last a long time. With an aggressive alignment, you will have to rotate them more often, but then you would with any tire in that situation. They did not do well in deep snow as they became packed pretty quickly- but with a light snow they did just fine with my limited slip rear end.

Initial Review, 4,000 Miles on Tires After selling my 2005 Prius with lowering springs, rear sway bar, under bracing and 17" wheels (Primacy MVM4 tires), I was a bit disappointed when I purchased a 2012 Prius that came equipped with Yokohama AVID S33D tires. The ride was nothing to write home about, the traction was a bit unpredictable and the car was more apt to tramline than anything else I had ever driven. I immediately swapped out the tires thanks to Yokohama's customer satisfaction guarantee and I installed the AVID Ascend in their place. The wet/dry gripe is pretty incredible for a tall 15" tire. Road noise is low most of the time with minimal pinging on expansion joints. Fuel economy is comparable to the OE AVID S33D but everything else about the Ascend is superior. Now if they last as long as Yokohama claims they will then they will have a winner on their hands. :) It should be noted that steering response and overall handling seems better than the Energy Saver A/S. if you want a better handling tire then get the Ascend. If you want max MPG then take a look at the Energy Saver A/S. Read All Reviews for This Tire | Write a Review for This Tire |

Suspension Shopping for my BMW 740i Part II
Having already c
hosen the Eibach Pro-Kit Spring Set for my 1997 740i, it's time to turn my attention to the the shocks and struts, known collectively as dampers. The available options include the Bilstein Touring Class, Bilstein Sport and KYB GR-2.
The Touring Class and GR-2 are similar to one another in that they're both premium quality replacements for the stock dampers. They are valved about 10% firmer than the originals to account for the wear that accumulates in other suspension components over time and their goal is to provide ride and handling that equals or exceeds the Original Equipment.
The Bilstein Sport is a high-performance shock absorber designed for use with lowering springs. The mono-tube design, while more expensive to produce, has advantages for heat dissipation, longevity and consistent performance.
Do I spend the money on the Bilstein shocks or save some cash and go back with a factory-equivalent part? The Bilstein Sports are the only replacement shock absorbers that are officially recommended to use with the Pro-Kit springs. Using the Touring Class or GR-2 with lowering springs would void their warranties. While this wouldn't be the first warranty I've ever voided when modifying a vehicle, I think that if I'm going to go through the trouble and expense of replacing them, it's worth doing it right. The Bilstein Sport was the winner and will make a great addition to my BMW 740i.

Initial Review, 2,500 Miles on Tires First, this is a modified 850 GLT; chipped, cold air induction w/K&N filter, IPD blue springs, sway bars, yellow Konis, and right now sporting the "autotragic." As you might correctly surmise, I am a somewhat feisty driver. These tires are 225/40-17's on the Sport 5-spoke F7 7.5x17 wheels. I haven't had a tire off to weigh the wheels, but I would be very surprised if they only weigh 20.8 lbs, but they seem to be stiff and are attractive without being gaudy. These are without any reservation THE BEST tires I've ever owned. I don't know how long they'll last, and the 9's I gave them for noise and ride, well, heck, they're a performance tire and my car is MUCH stiffer than stock. Fair is fair. I'm 56 and have driven at least 750k miles in my life and have never had a better tire. I'm in Seattle; wet performance was a serious consideration..these are nothing short of magnificent in the wet, and, even though they're not designed for snow, they're okay. In fact, their performance at around freezing doesn't seem to be significantly diminished. In contrast, the General UHP is definitely affected by lower temperatures. Of course, the UHP is about 1/3 the price! I have the UHP's on my Miata and like them pretty well-much better than the stock Bridgestones. And the Michelins are stunning on dry pavement. I definitely WILL buy these again, and I highly recommend them. In fact, a good friend just put a set on his 2007 Audi A4-chipped, with coilovers, and loves them. I believe he bought 245/35/19's for 19x8.5" rims. One caution-the 225/40/17's DO require a lip roll on the 850 as well as some trimming of the fender liner-the 215's probably would fit without mods.

Springs Sagging or Worn Out?
I received the following question in one of the forums I help moderate: "I have 137,000 miles on my car. I've heard that some people experience sagging springs. Under what conditions, if any, do springs wear out and how can I tell other than a lower ride height?"
Springs support the weight of a vehicle and over time can certainly sag and result in lowered ride height and reduced body control. While you may never "need" to replace springs (short of one being broken) on your vehicle, 137,000 miles is quite some time for the Original Equipment. You would likely see a noticeable improvement by replacing your springs after this amount of driving and time supporting the vehicle's weight. While you're replacing these suspension components, consider the Eibach Pro-Kit Spring Set.

Below are a few areas that will improve by replacing worn out springs with a new set of lowering springs:
- No more bottoming out
- Reduced body roll
- Reduced pitch and dive when braking and accelerating
- Better handling and steering feel

Initial Review, 1000 Miles on Tires These tires are a beast on ice. I climbed a hill that was completely covered in ice without one hiccup in traction (to be fair, it was paired with Subaru's incredible AWD). Where I live I only get maybe 2-3 significant snow falls a year along with a few 1-2" snow falls. Along with my WRX being a daily driver, I have zero need for a dedicated snow and summer tire setup. This is a nice blend of the two in one set of tires that offers good performance in both. Of course, don't except the same level performance from dedicated tires. However, the DWS is more than enough for the average driver. Read All Reviews for This Tire | Write a Review for This Tire | ||||

Initial Review, 10000 Miles on Tires For the price, these tires cannot be beat. I purchased these because I wanted something cheap that I could have some fun with on my hatchback. I have put about 10,000 miles on them, highway and city. They are perfectly balanced between being soft/sticky while retaining wear resistance. My only complaint with them is that at high speeds, you can feel some lateral play in the sidewall when starting to corner, but once you're locked into the corner you cannot feel it at all. My car is lowered with STIFF springs so when I'm in a hard corner the tires take 100% of the abuse, even still I have taken many hard corners and done quite a few accidental burnouts on hard launches, but the tires have still shown no signs of wear. It sounds like the people who reviewed this tire and rated poorly had alignment issues. My recommendation is to mount them, balance, and get your alignment done! rotate them every 6,000 miles and it should be a pretty trouble free tire after that.

Initial Review, 8000 Miles on Tires With 32lbs of factory reccomended pressure for the first 2000 miles the tires handled and cornered great but had tire squirm. Raised the pressure to 35lbs and the squirm dissapeared. The tires firmed up and handle and corner even better now. It finally snowed here and the tires were very slippery on the snow and ice. Lowered the pressure to 28lbs and now they handle the snow and ice better. Now they are predictable on the ice and have better traction on the snow. Lower pressure gives the tires a little more flex. I like these tires and will overinflate 3 lbs in the summer spring and fall, but underinflate in the winter.This is good to do for most light weight cars.

Lowering Your Ford Mustang
In addition to custom paint jobs and aftermarket wheels (rims), many Mustang owners are opting to lower their cars for more aggressive handling and appearance. Due to the flexibility of the late model Mustang chassis, there are several ride height and stiffness options available.
Depending on the version of Mustang, there are several options for lowering from standard non-adjustable springs to fully adjustable coil-over kits. Coil-over kits offer the height and dampening adjustability that is not possible with a spring-only application.
It's important to note that when changing a vehicle's ride height, alignment adjustments will be needed for your vehicle. For lowering, this typically includes reduction in camber to counter the camber increase caused by shorter springs. For the newer Mustang, a set of camber bolts will do the trick for the front and an adjustable panhard bar or trailing arm for the rear.
When you're looking for Mustang shocks, springs, coil-over kits or other suspension parts for your ride, be sure to shop by vehicle to find the parts that are a great fit.

Initial Review, 47000 Miles on Tires This review is for the Jeep's OEM GY Fortera tires but pertinent since I am replacing them with identical tires. I live in a rural area of SE MN and was satisfied with these tires in wet weather and most winter driving, my only minor ding is for deep snow so I was considering a switch to Yoko ATS or Mich ATS @ 30-60% price premiums. However there was a very good deal on theh Forteras with a rebate and I was convinced to go with them again. My rationale is they are very good handling, quiet, do very well in city/highway (freeway or rural, rarely off road for me). With regular rotations one would get > 50,000 mis & also get good gas mileage vs unknown loss in mpg going to an ATS/all terrain style tire.

When Should I Put on My Winter / Snow Tires?
ere for most, it is coming. Is it too early to install your winter / snow tires? I get this question often and the answer varies depending on a few factors. In my opinion, the most important issues to consider are climate and the type of winter / snow tire that you're using. Climate is arguably the most important factor in deciding when to install your winter snow tires. A driver in Alaska would install their winter tires earlier in the year than a driver in Illinois (and leave them on longer into the spring, as well). This is not only because some areas get snow before other parts of the country, but due to the fact that temperature also plays a role. It's a good time to consider installing your winter / snow tires when average highs are consistently below 50º Fahrenheit.
Most winter tires are designed to operate in lower ambient temperatures and may wear more rapidly when driven aggressively on warm pavement. This is especially true for more severe-duty winter / snow tires that we categorize as Studless Ice and Snow, including the Bridgestone Blizzak WS70 and Michelin X-Ice Xi2.
As mentioned above, Studless Ice and Snow tires like the Blizzak WS70 tend to wear more rapidly in warmer temperatures due to their soft compound and heavily siped tread patterns. Performance Winter / Snow tires like the Bridgestone Blizzak LM-60 can handle higher temperatures with less rapid tread wear compared to Studless Ice and Snow tires. Therefore, one can install Performance Winter / Snow tires earlier in the year and leave them on longer with less effect on wear. And to see how these winter performance tires perform, check out our Tire Survey Results.
If you don't yet have a winter tire setup, check out our snow tire prices and create a Winter / Snow Tire & Wheel Package for the ultimate in convenience, as you can install them yourself without waiting in line at auto tire stores.
How to Choose a Suspension Upgrade
The most popular upgrade for cars and trucks is new custom wheels and tires. After that, suspension upgrades are very common on both late model and older vehicles. Typically, drivers will want to simply raise or lower their car or truck for aesthetic reasons, but there are often performance reasons for suspension upgrades, as well.
Raising, often referred to as lifting, is most common on trucks and jeeps. In addition to creating a taller ride height, this is regularly done for performance reasons such as allowing for larger wheels and tires than what the factory (O.E.) suspension will allow.
There are two primary ways for lowering a vehicle: lowering springs or an adjustable coil-over suspension kit. Both of these options will give the car a lower center of gravity and stiffen the car's chassis, which will allow for less body roll in corners and improved handling and cornering. Coil-overs give the added advantage of ride-height adjustability and with certain models, dampening adjustability for fine tuning the balance of ride quality and handling.
Whether you're looking for performance shocks, gas shocks or other products to upgrade your suspension, it's important to consult with an expert. Changing a car's suspension will require alignment adjustments and may create fitment challenges with your custom rims (wheels) and tires.
Great Handling with KONI FSD Damper Set
Normally you'll start to notice damper wear approximately between 75,000-125,000 miles. The exact point when changes occur varies based on how you drive and the conditions of the roads you encounter. Damper wear happens gradually, therefore it can be difficult for a driver to sense it. It may be helpful to have someone else drive and evaluate your vehicle as another driver would have more of a "tabula rasa" perspective.
When the time comes to replace shock absorbers, you should get a damper that gives you proper control in the curves and smooth ride on bumps, tar strips and different road conditions. Proper handling, however, requires a higher rebound setting. A higher rebound setting means a firmer ride on bumps as the vehicle chassis will slam back down as its springs expand.
With older damper technology, most shock absorbers were designed to offer a good ride or good handling. What if you want both? KONI's FSD (Frequency Selective Damping) Damper Set provides lower rebound forces on higher-frequency piston movements (bumps) but higher rebound forces on lower-frequency movements (turns). KONI originally engineered FSD technology for the Lamborghini Murcielago and FIAT is using it on the new North American FIAT 500 Abarth. In our testing we found the KONI shocks with FSD technology provided our E46 test cars with an amazing balance between ride on our rough northern Indiana roads and proper handling on our autocross track. Although the FSD worked well for us as BMW shocks, they're also compatible with a variety of vehicles including, an Audi A3, MINI Coopers (both R53 and R56), the Mazda 3, Volvo S40, VW Jetta and VW Rabbit.
Thinking about lowering your vehicle when you replace dampers? Take a good look at KONI FSD Damper Set & Springs which combines FSD's with Eibach Pro-Kit Springs.

Which Shocks Are Right for My Car?
Have you ever felt that your car bounces more after you go over a bump? It just doesn't feel as connected to the road as it did when it was new? Shock absorbers are an expendable item that has a big effect on your ride quality. When it comes time to replace shocks, you're going to have access to your springs. This is a great time to add lowering springs. Not every shock is designed for all driving circumstances. There are two major categories for aftermarket shocks: performance and touring.
- Performance shocks give the firmer ride, and help reduce body roll. They are often combined with lowering springs for the ultimate handling combination.
- Touring shocks are more focused on a soft, compliant and comfortable ride. Touring shocks add to that supple, luxurious ride by soaking up more impacts and road imperfections.
- Compression - The collapsing stroke of a shock, directly correlated to the movement of your axle.
- Rebound - The return stroke of a shock, directly tied to vehicle pitch and ride quality. To learn more about shocks check out, "Damper Dynamics."
Take a look at a few of the shocks available at Tire Rack:
- KYB Gas-A-Just: An Original Equipment replacement shock.These are your excellent-value option, as they are self adjusting.
- KYB Monomax: Increased load control, and a firm planted feel for your light truck or SUV. These shocks have been known to offer a firmer ride, but the trade off is better control. These shocks are self adjusting. They completely transformed my Chevy Blazer back to the consistent like-new handling I missed.
- Koni STR-T: A cost-effective performance shock, designed to offer better handling, without a harsh ride.
- Bilstein 5100 : Designed with the lifted truck or SUV in mind. These are ideal for your Jeep or pickup truck with mild body and suspension lifts. The articulation in off-road circumstances is superb.
Don't Want Any Lip
You can save yourself a lot of headaches and/or tire damage if you are ready in advance for the side effects of going lower and wider. The number one obstacle can often be those pesky fender lips. If you reach your hand under the arch of your fender you will typically feel a lip at a 90 degree angle to the arch that can protrude into the fenderwell by an inch or more. This extra material is there to add structural rigidity to the fender arch. If the effects of lowering and widening your car causes interference with this pesky little strip of metal, have no fear, I have the answer.
The Tire Rack Fender Lip Rolling Tool is a professional quality tool designed to maximize the wheel well clearance when upgrading to larger tires with lower positive offset wheels. The tool can also be used to repair the wheel well area and lip damage.The Tire Rack Fender Lip Rolling Tool fits all four and five-lug wheel hubs up to 120mm bolt circle with hubs up to 72.5mm, however it will not fit Porsche. The forming arm adjusts from 14" to 22.75" to roll lips almost flat. The plastic coated (Delrin®) roller forms the fender lip without damaging the paint. In addition, using a high temp hair dryer or heat gun with the Fender Lip Rolling Tool will minimize the potential for paint damage during use. You can see how easy it is to set up and use by reviewing the User's Guide (PDF).
Coil-Over Kits for 2007-2010 BMW M3 Coupe
A coil-over suspension kit incorporates precisely matched coil springs and dampers in a compact solution to provide maximum performance. In addition to improved handling, these coil-over suspension solutions reduce the unsprung weight of a vehicle. These improvements translate to faster lap times and improved daily driving comfort.
Coil-overs can also be a great solution for lowering your car with upsized custom wheels (rims) and tires. The ability to fine tune the car's ride height can be a great way to overcome many challenging wheel fitments.
There are several options including kits from KW and H&R that can adjust both the ride height and dampening:
