Product Details

If you're looking to give your 2007-2008 Audi RS4 a more aggressive stance and improved handling, the KW H.A.S. (Height Adjustable Spring) kit is a smart alternative to traditional lowering springs. This system lets you dial in the exact ride height you want, even after installation, giving your RS4 a custom look and feel without sacrificing the factory electronic suspension's functionality.

KW engineers these kits with vehicle-specific spring rates, using high-strength chrome-silicon steel that's designed to work harmoniously with your car's original dampers. This means you get a sportier, more responsive feel without compromising the driving dynamics that make the RS4 a performance machine. The kit also includes application-specific bump stops and dust protection systems to help safeguard your factory suspension components from road debris and wear. Unlike fixed lowering springs, the H.A.S. system offers continuous ride height adjustment within a tested range, allowing for millimeter-precise tuning of each corner.

This kit is designed to integrate seamlessly with your RS4's factory electronic suspension, ensuring all driver assistance systems and comfort features remain fully operational. Comprehensive testing on the Nurburgring Nordschleife and at KW's own driving dynamics test center ensures these springs meet high performance standards.
