KW H.A.S. Audi RS4 (B7/8E) Convertible/Avant

This kit includes KW H.A.S. (Height Adjustable Spring) systems for your 2007-2008 Audi RS4. You'll get vehicle-specific springs made from chrome-silicon steel, along with KW's height adjustment mechanisms and application-specific bump stops with dust protection. This setup is designed to work seamlessly with your factory electronic suspension, whether your RS4 has adaptive dampers or standard ones.

Unlike traditional lowering springs that offer a fixed drop, the KW H.A.S. system lets you dial in the ride height with millimeter precision, even after installation. This means you can achieve a more dynamic look and feel without sacrificing the sophisticated handling your RS4 is known for. KW engineers develop these spring rates and parameters specifically for your car's OE suspension dampers and wheel loads, ensuring a sporty yet harmonious driving experience. Extensive testing on the Nurburgring and in their own 7-post driving dynamics test center backs up their approach.

With this kit, you can expect improved steering behavior and a more agile response from your vehicle. The included bump stops and dust protection elements are crucial for safeguarding your factory suspension components from road grime and debris, helping to prevent premature wear. This system offers a continuous adjustable ride height within a tested range, providing a significant upgrade over conventional lowering springs.
