KW H.A.S. Kit 2019+ BMW 8 Series (G15) M850i xDrive

This KW H.A.S. (Height Adjustable Spring) kit includes high-quality springs made from chrome-silicon steel, along with KW's ride height adjustment mechanisms. You also get vehicle-specific bump stops with dust protection systems designed to keep your factory suspension clean and free from road grime. This kit is designed to work with your BMW M850i xDrive's original electronic suspension, ensuring all driver assistance systems and comfort features remain fully operational.

Unlike traditional lowering springs that offer a fixed drop, the KW H.A.S. kit lets you fine-tune the ride height of your M850i xDrive with millimeter precision, even after installation. The spring rates are carefully engineered to match the specific characteristics of your factory dampers and wheel loads, providing a more agile steering response and improved handling without compromising the vehicle's dynamic driving behavior. KW's engineers put these spring sets through rigorous testing, including time on the Nurburgring Nordschleife and at their 7-post driving dynamics test center, to ensure they perform harmoniously with your car's original suspension components.

By using these height-adjustable springs, you can achieve a sportier look and feel for your M850i xDrive while maintaining the comfort and functionality of its advanced factory suspension. The included dust protection elements and spring perches are set to achieve the maximum technically possible lowering, typically limited by the factory dampers.
