KW V3 Coilover Kit For Audi S4 (8E/B6 QB6) Convertible & Avant; Quattro

Sporty and personalized with adjustable rebound dampening. This system is designed for the driver who requires not only determining the individual lowering of their vehicle, but having the ability to adjust the damper settings to fine tune the system to their needs.The adjustable rebound damper allows adjustment of the pitch and roll of the vehicle adapting it to one's own driving preferences.

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 volume 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.
