KW H.A.S. BMW 20+ 8 Series Gran Coupe

This kit includes KW Height Adjustable Springs (H.A.S.) designed specifically for your 2020-2025 BMW M850i xDrive Gran Coupe. You'll also get vehicle-specific bump stops with dust protection systems, and the necessary spring perches and adjustment mechanisms to set your desired ride height. This system offers a way to lower your car without being locked into a fixed height, giving you the flexibility to fine-tune the look and stance of your M850i.

Unlike traditional lowering springs, the KW H.A.S. system lets you adjust the ride height with millimeter precision even after installation, similar to a full coilover setup. KW engineers use high-strength chrome-silicon steel for the springs, with rates carefully matched to your car's factory dampers and wheel loads. This ensures that your car's steering response and overall handling become more agile while maintaining the intended driving dynamics. Importantly, all of your vehicle's factory driver assistance systems and comfort features, including adaptive electronic suspension, will remain fully operational and work harmoniously with these springs.

The included bump stops and dust protection help shield your factory suspension components from road grime and debris, contributing to their longevity. KW tests these spring setups extensively on the Nurburgring Nordschleife and in their own 7-post driving dynamics test center to ensure they perform as expected. This is a solid option if you want a sportier look and improved handling without compromising the sophisticated electronic systems in your M850i Gran Coupe.
