KW Competition 2A EXR
The KW Competition 2A EXR are the consequent further development of the 2-way adjustable racing dampers for the use in GT4 and TCR racing. STR2A stands for SingleTube damper technology with 2-way adjustable valve technology and separate reservoir. The damper forces are generated on the working piston and the compression valve in the expansion tank. Due to the position-independent reservoir, the gas volume can be adapted to the damper stroke and higher damping forces can be realized with a lower static gas pressure than with 1-pipe gas pressure dampers without separate pressure stage bottom valve. The KW Competition 2A EXR are also available for McPherson axles in upside-down version STR2A 40P and STR2A 45P with 40mm or 45mm plain bearings.

KW Competition 3A
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.

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)

KW Competition 4A
The new KW Competition TTRSPW4A TwinTube damper has a precise 4-way damper adjustment in low speed and high speed forces of the compression stage as well as the rebound stage with 18 clicks each. Its functional principle with solid slave piston allows an direct reaction even at the lowest strokes. The new KW valve technology with plate springs allows an individual characteristic design and covers a large force range of 1000 to 8000N. Depending on the requirements, the modular built damper can also be extended with an additional blow-off characteristic. The valve arrangement ensures a cavitation-free function at a low gas pressure. Due to its construction-independent use possibilities, the damper is suitable for any type of non-wheel-guiding axle constructions such as double wishbone or pushrod suspensions. The external reservoir is connected to the damper either directly as a piggyback or via a hose connection.
