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:
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.

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.

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.
Listed below are a few terms that will help you better understand the characteristics of a shock adjustment:
- 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.

Coil-over suspension kits represent the top end of the suspension market, giving the driver the most flexibility in adjusting both the ride height and "firmness" of the shock absorbers to fine tune the handling of their vehicle. Sounds like a great option to have right? Well, the answer lies in how and where you drive your vehicle.
The first thing to remember is that any component that lowers the ride height of your vehicle will affect ride comfort (see a previous blog post titled
"What Should I Expect from Lowering Springs?"). Even the most modest lowering spring (
1.0" of drop or less) will affect ride comfort, but any coil-over setup will have a much more aggressive spring rate which translates to a firmer ride. In my mind, the coil-over suspension is intended for a driver that wants to maximize the handling of the vehicle in "track" conditions and also have the flexibility to adjust ride height (and damping rates) to suit track conditions. If local road conditions are poor, coil-overs will make a rough ride even rougher!
The Eibach Multi-Pro Coil-Over R2 and the KW Variant 1 have the least "aggressive" spring rates, which will minimize the change to ride comfort but still improve handling and allow you to adjust your ride height for the perfect stance.
The Bilstein PSS Coil-Over Kit and KW Variant 3 represent the elite in coil-over systems and provide the greatest range of adjustability for ride and ride height.

50 years ago,
Bilstein revolutionized the shock industry with their monotube gas pressure shock absorber technology. And to this day, Bilstein shock absorbers lead the market.
Bilstein offers a number of gas shock absorbers, but also single and twin tube McPherson strut style suspensions that are equally impressive. No maximum load challenge goes unaccepted, thanks to specific design techniques that provide high durability.
But will they fit your vehicle? All Bilstein shocks and struts are built based on the individual fit and performance needs of a vehicle. Search by vehicle to see if they are a fit for yours. And with an excellent lifetime warranty, you can rest assured you'll experience continual satisfaction with the product.

The most integral part of your suspension system is, surprisingly, your shock absorbers. They adapt to the roads and your vehicle's weight, as they must be able to absorb every last pothole and bump your vehicle comes in contact with. But, did you know that some performance shocks are adjustable?
Adjustable shocks allow for a certain level of fine-tuning, which brings the vehicle to the ride comfort and handling preferences of the driver. It also allows the driver to adjust dampening, and that compensates for wear. (

After hitting 60,000 miles on the my Mini Cooper S, I could tell it was time (and maybe a little late) for replacement shock absorbers. The car wasn't settling as quickly after dips in road and small bumps were becoming much more noticeable. I considered shocks from a few different ma

nufacturers like
KYB, KONI and Bilstein. But after reading the shock absorber reviews on
tirerack.com, I decided to go for the
KONI FSD Damper Set. I have had great experiences in the past with Koni shocks, so I had high hopes for the Damper Set.
The customer reviews were correct...the Koni FSD Damper Set was fantastic. The handling was improved with quicker response to steering inputs and less bounce after bumps or unsettling maneuvers. But true to the customer feedback, the ride quality actually improved absorbing bumps in a more subtle fashion than the stock shocks.
The Koni FSD Damper Set is a definite step up from standard shock absorbers, but there are also a huge step up in ride quality and performance.
