KW Clubsport Kit Audi S4 (8E/B6 QB6) Sedan Quattro

The composite spring perch, made from a wear-resistant polyamide with a stainless-steel insert, is a smart choice for preventing oxidation while maintaining strength. This KW V3 Clubsport coilover kit is built for serious performance, especially when you're running high-performance tires like DOT-Rs. It’s designed to give you the edge whether you're hitting HPDE days, time attack events, or club racing. The setup was fine-tuned on the Nordschleife, and the continuously adjustable ride height lets you dial in corner weights or make quick setup changes trackside.

What really sets this kit apart is the TVR-A and TVC-A valve technology. This means you can independently adjust both the rebound and compression damping. This level of control lets you fine-tune the steering response, stability, grip, and overall handling to match your car's specific setup – think weight, tire characteristics, and track conditions. The solid aluminum unibal top mounts are another key detail, minimizing deflection for better steering feedback and offering camber adjustability to further refine your alignment.

KW builds these Clubsport coilovers by hand in Germany, and each one gets its own serial number. They're dyno-tested to ensure accuracy and preset to their recommended settings before they ship out. This kit brings road-legal motorsports technology directly to your Audi S4, featuring track-focused linear springs and dampers matched for aggressive driving.
