KW H.A.S. BMW M3 (E93) Convertible

When you want to lower your 2008-2013 BMW M3 Convertible but want more flexibility than fixed lowering springs, the KW H.A.S. (Height Adjustable Spring) kit is a smart choice. This system lets you fine-tune the ride height of each corner with millimeter precision, even after installation, giving your M3 a sportier stance and improved handling without sacrificing the factory electronic suspension's functionality.

KW engineers these springs using high-strength chrome-silicon steel, with spring rates carefully matched to your M3's specific OE dampers and wheel loads. This ensures a harmonious driving experience where the improved agility and steering response don't come at the expense of ride quality or the integrity of your factory adaptive suspension. The kit includes application-specific bump stops and dust protection systems to help shield your factory dampers from road debris, extending their life. Unlike conventional lowering springs, the H.A.S. system offers a continuous, tested range of height adjustment, allowing you to achieve the perfect look and feel for your performance vehicle.

The development process for these springs includes extensive testing on the Nurburgring Nordschleife and at KW's own 7-post driving dynamics test center, ensuring they meet rigorous standards for performance and durability. This kit is designed to work seamlessly with your M3's factory electronic suspension systems, maintaining all driver assistance and comfort features.
