KW Competition 3A Coilover

KW Competition 3A

3-way adjutable racing damper technology with reservoir





KW Competition STRS3A are SingleTube dampers with reservoir, coil spring valve technology and 3-way damper force adjustment. The basic compression stage has an individually pre-configurable midspeed valve, in addition to the high speed and low speed compression adjustment, the transition point from a progressive to a digressive characteristic curve can be varied. The adjustable rebound stage can be optimally configured for the intended purpose by an extensive number of needle valves and coil springs with a linear, progressive or digressive characteristic.
The STRS3A technology convinces by a maximum reliability and low maintenance effort. For McPherson-axles with 40mm Inverted damper cartridge as STRS3A 40P plain bearing or in the unique friction-optimized linear bearing version STRS3A 40L. For the rally use with standpipe diameter 45mm and 50mm available as KW Competition STRS3A 45P or STRS3A 50P.



Examples of application:
Porsche 991 GT3 R, BMW Z4 GT3, Scuderia Cameron Glickenhaus SCG003 C
Self-built race cars for circuit, hill, slalom and rally.

KW COMPETITION 3A / STS3A 40L




Our 3-way adjustable SingleTube dampers are in addition to the conventional upside-down versions also available as special linear bearing solution STS3A 40L, which is characterized by a lower friction and a low breakaway torque. As wheel-guiding McPherson struts are exposed to highest loads during cornering and braking, the advantage of KW linear bearings at increasing transverse forces (lateral forces) is up to 87% less friction compared to plain bearings.





Advantages linear bearing:
  • 40mm inverted damper cartridge
  • High stability & camber stiffness
  • Low brakeaway torque
  • Up to 87% less friction under transverse force (lateral force)
