KW H.A.S. Height-Adjustable Spring Kit | BMW F90 M5 (2018–2023)

KW H.A.S. Height-Adjustable Spring Kit

BMW F90 M5 | 2018–2023

Lower your BMW F90 M5 while retaining the factory adaptive electronic dampers with the KW H.A.S. Height-Adjustable Spring Kit. Unlike conventional lowering springs with a fixed drop, the KW H.A.S. system allows the vehicle’s ride height to be adjusted within its approved range even after installation.

Designed specifically around the factory F90 M5 suspension, the kit provides a lower and more aggressive stance while improving steering response and overall handling characteristics. Factory driver-assistance systems, comfort settings, and electronically controlled suspension functions remain operational.

KW uses vehicle-specific chrome-silicon steel springs with spring rates engineered to work with the original dampers and axle loads. The included height-adjustment mechanisms allow precise setup while maintaining balanced, performance-focused driving behavior.
