Cutting-edge motorsports technology for more performance on the road. With independently adjustable compression and rebound dampening the Variant 3 damper setup can be tuned to your own driving preferences or vehicle modifications such as weight, tire characteristics or additional chassis bracing. True performance optimization is only possible with this unique, patented system. For example, the compression dampening force can be increased to optimize grip from the tires, or improve cornering behavior and reduce squat without influencing the rebound dampening characteristics that are optimally tuned to the spring rate. Specifically Engineered Setup – Vehicle Specific with Separately Adjustable Rebound and Compression dampening The KW Variant 3 "inox-line" coilover kit is the ideal tool for performance-oriented drivers and experienced tuning enthusiasts who place a strong emphasis on the overall performance of their suspension. The Variant 3 features patented TVR-A and TVC-A technology that provides separately adjustable rebound and compression dampening. The extensive adjustment range of the independently configurable rebound and compression make it easy to directly influence the steering behavior, directional stability, grip and handling characteristics for confident and repeatable results at the limit of driving dynamics.
TVR-A Technology The two-stage, patented TVR-A (Twin Valve Rebound - Adjustable) technology enables a small volume of oil to flow through an adjustable, conically shaped, low-speed bypass during low damper speeds, while in the case of higher damper speeds, the main rebound stage valve opens allowing a larger volumn of oil to flow. This provides a big improvement in terms of ride comfort without influencing the safety-relevant high-speed range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.
TVC-A Technology With 12 precise clicks, the KW Variant 3 coilovers utilize TVC-A (Twin Valve Compression - Adjustable) technology and can increase or decrease the flow of valve to achieve either more or less low speed compression dampening. During sudden high speed impulses the spring loaded needle valve and the spring loaded main valve open to their maximum valve cross section, acting as a digressive blow-off characteristic to avoid transmitting undesired forces through the suspension into the chassis. This provides a better platform for the vehicle body and at the same time offers more comfort than with conventional valve technology during high wheel acceleration. The dampers come preset to our baseline shock settings right out of the box providing an optimal starting place for your car while providing a wide adjustment window for true performance optimization.
Continuous Ride Height Adjustment With KW Variant 3 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension with adequate travel after your car is lowered. Even after years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar.
The Benchmark of Coilovers As with all KW coilovers our engineers develop vehicle specific damper and spring specifications which undergo comprehensive testing on the Nürburgring Nordschleife and in our KW 7-post Driving Dynamic Test Center. With a KW Variant 3 coilover kit the driving experience is more dynamic and direct.
You are not buying a mass produced, generic coilover kit, a KW coilover has been developed specifically for your particular vehicle. As a manufacturer, KW uses only its own resources, high quality components and the damper technology that has all developed in-house. With the KW Variant 3 "inox-line" coilovers, rolling motion of the body will be reduced during compression giving you the benefit of more direct handling and confidence while driving.
Our Experience Means Your Driving Pleasure For over 25 years, KW automotive has been the market leader and driving innovation as a manufacturer of individual suspension solutions for the road and in all types of motorsports. No matter where in the world, gearheads, automobile manufacturers and reputable tuners rely on our KW coilovers "Made in Germany".
