The KW Suspension Variant 3 Coilover System is state-of-the-art technology derived from motorsports competition for a more precise performance on the road. The separate and independently adjustable rebound and compression Dampening allows for individual suspension setups with different uses and preferences. The unique patented system with its two-stage valves allows a rebound Dampening adjustment (comfort) and a compression adjustment (driving dynamics) in the low-speed range, while the high-speed range which controls the driving safety, is fixed. _x000B_ _x000B_ _x000B_Features: _x000B_ _x000B_Dampening technology with individually adjustable rebound and compression _x000B_Inox-line stainless steel technology _x000B_Individually height adjustable _x000B_Adjustment parameters approved by TUV _x000B_High-quality components for long durability _x000B_Infinitely variable rebound Dampening adjustment _x000B_14-way adjustable compression Dampening _x000B_Unique, individually working Dampening force adjustment _x000B_Comprehensive Instructions for easy installation _x000B_ _x000B__x000B_ _x000B_Rebound Adjustment _x000B_ _x000B_Being vehicle-specifically possible, the rebound Dampening 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 Dampening range. _x000B_ _x000B_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. _x000B_ _x000B_ _x000B_Compression Adjustment _x000B_ _x000B_The compression phase adjustment is carried out at the lower end of the shock absorber via KWs 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. _x000B_ _x000B_In the compression range, the driving behavior of the vehicle is drastically influenced. An increase of the Dampening power supports the vehicle already during compression and therefore avoids rolling and pitching, significantly improving the directional stability. _x000B_ _x000B_ _x000B_Porsche 997 Carrera / S Excl Convertible w/PASM 05+ Kit Features: _x000B_ _x000B_Adjustable Compression & Rebound Dampening _x000B_Stainless Steel Construction _x000B_Lowers 20-45mm Front _x000B_/ 20-45mm Rear _x000B_Spring Rates: 230lbs/in Front _x000B_/ 740lbs/in Rear _x000B_Limited Lifetime Warranty _x000B_ _x000B__x000B_ _x000B_NOTE: Electronic Dampening control has to be deactivated.
