KW Coil-Over kits are the final answer to your suspension needs. For most BMW applications, KW makes a kit that will perfectly suit your expectations for ride, handling, fitment, and quality. KW's single-minded focus on coil over suspensions ensures proper vehicle-specific engineering with the correct suspension travel, fitment with OE or KW mounts, and ease-of-use. KW uses inox-stainless steel or aluminum on nearly all of their parts to ensure the maximum level of corrosion resistance. Every Variant kit has been tested and certified by Germany's TUV and comes with a limited lifetime warranty. Their fresh approach to complete suspension assemblies has won them praise from forums and shows to racetracks around the globe. KW uses different levels of kit specification - ranging from mild-mannered to hardcore track-only designs.
Variant 1 - Factory Pre-set Damping - Each V1 Coilover has dampers perfectly tuned for the springs included with the kit. This delivers a comfortable but sporty and controlled ride without being jarring or uncomfortable.
Variant 2 - Rebound Adjustable Damping - The V2 kit adds rebound control to the V1 kit. By making the rebound of the shock adjustable, you are more able to tune the handling of the car to suit your needs. Rebound works with the springs to help keep the tire pressed against the pavement. The compression dampening of the shock remains the same as V1.
Variant 3 - Rebound + Compression Adjustable Damping - The V3 coilovers give you full control over rebound and compression rates and puts you one step closer to a true race-ready suspension. Shock Rebound (infinite) and Compression (14 positions) are adjusted independently so you can precisely change the handling charactertistics to get the best fit for indivdual tracks to get the lowest lap times. Or adjust the settings to suit the ride/handling needs for the roads in your area. You've got full control!
ClubSport - Rebound + Compression Adjustable Damping, Front Adjustable Camber Plates, Track-spec Spring Rates - The KW Clubsport line is geared for track-focused cars where performance trumps everything else. These kits have stiffer springs with corresponding changes to the shock adjustment range, and front monoball bearing camber plates (for most BMW applications). Because of the narrow focus of this suspension, we recommend using it only on a racetrack. With solid mounts like monoball bearings you gain performance and agility in place of comfort. Shock, Rebound and Compression, and front camber are all adjustable independently so you can precisely change the handling charactertistics to get the lowest lap times for the track you're running. You've got ultimate control!
