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.

Details at a glance:

• SingleTube dampers
• Separate compression and rebound valve
• 2-way adjustable
• Damping adjustment: Rebound 16 clicks; Compression 15 clicks
• Extensive characteristic design
• Piston rod diameters: 18mm or 22mm
• Piston diameters: 36mm or 40mm
• Damper or height-adjustable racing coilover struts in STR2A-version
• McPherson-struts in inverted version STR2A 40P or STR2A 45P
• ressure compensation tank as piggyback (rotatable up to 360°) or with hose connection for an installation independent of construction
• Optionally: upgrade to 3-way adjustment

Competition 3A EXR
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.

• Pre-configurable compression-midspeed-valve
• Individual characteristic design for a linear, progressive or digressive characteristic
• Piston rod diameters: 18mm or 22mm
• Piston diameters: 35mm, 36mm, 40mm and 43mm
• Damper or height-adjustable racing coilover struts in STRS3A-version
