KW Competition kits
KW Competition coilovers are the number one choice of many top international race teams. The excellent combination of performance/price ratio and long standing history of successful victories and championships claimed by KW racing technology has been a su
The versatile characteristics of the KW Competition suspension kits accommodate a broad range of different pavement surfaces, radius of turns and elevation changes. The KW Competition kit has been the main-stay of many top teams racing at the most demanding race track in the world - Nurburgring Nordschleife, aka the "Green Hell".
Whether in the VLN, 24h Nürburgring, GT Asia, WTCC, FIA GT1, ADAC Procar - motorsports team every where teams rely on the suspension know-how of KW Competition.
KW's renown test center provides the ability for our competition department to progress in specific areas of vehicle suspension setup in a confidential environment. The hydraulic 7-post rig can be activated in various modes such as 7 post and 4 post sweep
Depending on the type of race car, between 50 to 100 measurements can be recorded each day.
There is no wear and tear on the vehicles as compared to the race track environments and racetrack fees, testing times are reduced significantly.
The KW test center is open to all teams regardless of their brand of suspension on their vehicle.
KW 2-way competition racing suspension
KW Competition 2 way suspension kits feature independent rebound and compression damping. They can be constructed out of galvanized steel housings where structural strength is a concern or lightweight aluminum, where weights savings is advantageous. The following damper versions are available.
- Twin tube technology with 15, 18 or 22 mm rod diameter
- including surge tank for an position independent installation
- including adjustable compression valve technology in the reservoir for additional damper stroke
- Mono-tube upside down damper cartridge with 40 mm standard bearing
The rebound adjustments are made at the end of the piston rod end and provide 16 precise clicks of adjustment. The compression adjustment is located at the bottom of the damper or on the reservoir and provides 12 exact clicks of adjustments. IN addition to a wide range of suspension systems. Custom orders can be accommodated for nearly every type of race car.

KW 3-way Competition racing suspension
The KW competition 3-way racing coilovers provides 3 independent features of adjustment. Low-speed rebound, high and low-speed compression adjustment. The unique valve technology of the 3-way damper system differs from conventional mono-tube damper shim package valve technology. This design also provides a maintenance-friendly service of the damper system.
Versatile in its design, the damper system performance remains consistent even through a high temperature environment and has been proven to be reliable. The Competition 3-way systems are designed on the mono--tube damper principle with an adjustable reservoir. Rebound adjustments are made through an adjustable needle on pre-adjustable valves.
Depending on which version (18 or 22 clicks), the compression level in the low-speed and high-speed range can be adjusted. The standard compression level is controlled by a pre-configurable blow-off valve. The 3-way Competition kits are constructed of high-strength aluminum. McPherson front struts are constructed as inverted dampers with 40mm and 45mm/55mm (for rally use) guiding tube diameters. Steel construction is an option for endurance racing applications.

The McPherson Technology
McPherson struts utilizing a 40mm damper cartridge provide a highly stable and laterally flex resistance construction. The inverted damper is guided in an outer tube housing via a standard bearing. Special linear bearings are optional and reduce any possibility of rod stiction. This is an ideal setup when racing with wide and soft compound race tires.
As wheel-guiding struts are exposed to maximum loads during cornering and braking, the benefit of KW linear guided bearings grow at increasing lateral force of up to 87% less friction compared to plain bearings.
Advantages of linear bearing:
- 40 mm inverted cartridge
- high stability and camber stiffness
- up to 87% less friction under lateral force
KW 7-post rig
At the KW test center in Fichtenberg, motor sport teams and industry partners have the opportunity to simulate suspension relevant race track sections on a hydraulic 7-post driving dynamics test rig.
