KW is one of the world's leading suppliers of performance orientated suspension systems, and features a wide range that covers nearly every vehicle platform. KW coilovers are particularly suited to the technically minded sport driver and are available in three damping variants. To compliment the KW coilover range, KW suspension also produces a range of sport suspension kits, springs and dampers. Impressive successes in international motorsport include series such as FIA GT, FIA WTCC, American Le Mans Series, 24h Nürburgring and many other motor sport series.
KW Exquipped Astra VXR KW has drawn upon its resources, experience and motorsport know-how to produce their road and race suspension kits. KW suspension is used on the Championship Winning Courtenay Sport Astra VXR Dunlop Sport Maxx Production Cup Car, and used on both our Production Touring Car Trophy 2011 entries. We also ran KW suspension on our 2013 Time Attack entry.

Compression (V3) and Rebound (V2 & V3) Adjustment

Compression and Rebound Adjustment As far it is vehicle-specifically possible, the rebound damping is adjusted by a spindle at the end of the piston rod. Mainly, the traction phase (rebound) controls car body vibrations and also influences handling and comfort in the low-speed damping range. By using the traction phase adjustment, the vehicle can be adapted to the requirements of the driver. Moreover the driving behavior can be regulated from comfortably rolling to sporty and tense with improved road holding characteristics.

The compression phase adjustment is carried out at the lower end of the shock absorber via our patented multi-purpose valve. The large number of pre-set parameters of this valve allows for a wide range of adjustment for individual use. The unique low-speed compression adjustment significantly distinguishes this technology from any other. In this compression range, the driving behavior of the vehicle is drastically influenced. An increase of the damping power supports the vehicle already during compression and therefore avoids rolling and pitching. The directional stability is significantly improved.

KW Clubsport Coilovers 2-Way

The KW Clubsport coilovers utilize the uncompromising transfer of technology from the world of motorsports to track day and street driving.
Designed for the more discerning driver who wants the best for their trackday car but with a level of suitability still for road use on occasion. The KW Clubsport Coilver kit is the next step up from the excellent but more road biased KW V3 kit with a more 'track-focussed' spec featuring matched springs with helper spring set up .

The KW Clubsport Coilovers combine KW's high-end racing technology with maintenance-free KW OEM components and TÜV certificate. This will provide you the ideal product to take full potential of your sports car during track days, sports car driving clinics, enthusiast drives on Grand Prix circuits and on tracks such as the Nürburgring Nordschleife.

Designed on the toughest race track in the world: The Nürburgring Nordschleife
The KW Clubsport coilovers provide the ability to adjust for different track surfaces, sharp turns and sharp elevation changes. The KW Clubsport is in its home environment on the famous twists and turns of the 20.8 km long Nürburgring Nordschleife circuit.

As a supporting suspension manufacturer to numerous different racing series. KW had claimed 6 ADAC Zurich 24-hour victories within 10 years at the famous Nürburgring circuit and the ADAC GT Masters 2011 Championship. More then 70 race teams are equipped with KW coilover systems in the VLN Endurance Championship series. These race teams rely on KW's racing expertise and experience for their vehicle setup. This information is mirrored in the development of the KW Clubsport coilover systems.

The KW Clubsport 2-way provides the user numerous adjustment settings. This allows to user to dial the suspension setup to his/hers driving style and to adjust or match the tire/wheel setup of the vehicle.

Rebound and compression dampening is independently adjustable by hand via the integrated click adjusters. Adjustable top mounts are optional on certain applications.

In contrast to anodized adjustable spring seats made of aluminum, at KW we use a durable polyamid composite collar with a stainless steel insert. So even with the influence from dirt particles, such as brake dust or sand grains, the polyamide composite collar will not be damaged.

KW Clubsport Coilovers 2-way Racing Technology

The rebound adjuster knob provides 16 precise clicks to personally dial in your desired vehicle setup. Thus allowing you the possibility to influence wheel/tire loads or take into concern chassis characteristics. Independent from rebound adjustment is the compression dampening, 12 precise adjustment clicks are provided to adjust the low-speed dampening. Most notably used to dial in wheel/tyre setup.

These adjustment features allow the user to dial in vehicle weight, wheel/tyre combinations, various road surfaces and environmental conditions.
