KW H.A.S. - 2021+ BMW M4 (G83) Cabrio; AWD including M4 Competition

With this KW H.A.S. (Height Adjustable Spring) kit, you get a set of four springs, vehicle-specific bump stops with dust protection systems, and the necessary adjustment mechanisms. This system offers a significant advantage over traditional lowering springs because it lets you fine-tune your vehicle's ride height even after installation, giving you a dynamic look and improved steering response without compromising your factory electronic suspension. KW engineers these springs using high-strength chrome-silicon steel, carefully matching the spring rates to your specific OE suspension dampers and wheel loads. This ensures they work harmoniously with your car's adaptive or electronic suspension systems, maintaining all driver assistance and comfort features.

The ability to adjust the ride height within a tested range, similar to a coilover setup, is a key benefit. This means you can achieve a sporty stance with millimeter precision. KW's commitment to performance is evident in their rigorous testing, including the Nurburgring Nordschleife and their own 7-post driving dynamics test center, ensuring a sporty yet balanced driving experience. This kit is designed to integrate seamlessly with your BMW M4's existing suspension, providing an improved driving behavior without sacrificing the vehicle's inherent dynamics.
