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

This KW V3 Clubsport coilover kit includes everything you need to significantly upgrade the suspension on your 2004-2007 Audi S4. You'll get the complete set of four adjustable coilovers, featuring Inox-Line stainless steel construction for lasting corrosion resistance. It also comes with solid aluminum unibal top mounts that offer camber adjustability, improving steering feedback by reducing deflection.

This kit is built for serious performance, especially if you're running ultra high-performance tires or plan to use your S4 for track days, autocross, or club racing. The core of its performance comes from KW's patented TVR-A and TVC-A valve technology. This allows for independent adjustment of rebound and compression damping, giving you precise control over how your car handles at the limit. You can fine-tune steering response, stability, grip, and overall handling to match your car's setup, like tire choice and weight distribution, and the continuous adjustable ride height lets you set corner weights accurately.

These coilovers bring race-track-ready technology to your street car, hand-built in Germany with a unique serial number. Each damper is tested before it leaves the factory and preset to KW's recommended settings, so you can get started with a solid baseline. The composite spring perches are designed to be wear-resistant and friction-optimized, further enhancing the durability and performance of the setup.
