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

KW automotive is well-known for bringing motorsports technology to the street, and their V3 coilover suspension kit for your 2004-2007 Audi S4 is a prime example. This kit is designed to give your S4 a significant boost in safety reserves and driving dynamics. By reducing pitching and rolling during load changes like cornering, braking, or evasive maneuvers, it helps shorten braking distances and provides a more connected feel to the road. You'll notice improved support and feedback, making everyday driving feel more secure and controlled.

What really sets the V3 apart is its ability to let you fine-tune the suspension to your exact preferences. The patented TVR-A (rebound) and TVC-A (compression) damping technologies allow you to adjust these settings independently. This means you can increase compression damping for more grip and better cornering without negatively affecting the rebound, which is crucial for maintaining optimal spring performance and preventing a loss of grip. The kit includes composite spring perches that are wear-resistant and friction-optimized, preventing oxidation and ensuring strength with their stainless-steel inserts. Plus, the Inox-Line stainless steel construction means these struts are built to resist corrosion for their entire lifespan, even with frequent adjustments.

This coilover kit is hand-built in Germany and each damper is dyno-tested to ensure accuracy before it leaves the factory. The kit also features elastomer bump stops with integrated dust protection to keep dirt and water away from the seals and piston rod, while also acting as dynamic load limiters to maintain ride quality. You'll receive a kit that's ready for performance optimization, allowing you to directly influence steering behavior, directional stability, and overall handling characteristics for confident driving, even at the limit.
