KW Height-Adjustable Spring Kit for BMW G87 M2, G80 M3, and G82 M4

Description

Upgrade your G8X-platform BMW M2, M3, or M4 with the KW Height Adjustable System (H.A.S.) — a premium suspension lowering solution that combines the benefits of conventional lowering springs with the tunability of adjustable ride height. Unlike traditional fixed springs, this kit lets you fine-tune your vehicle’s ride height even after installation, giving you total control over stance, ground clearance, and suspension balance. Engineered with vehicle-specific spring rates and threaded height perches, the system enhances handling dynamics while maintaining compatibility with your factory electronic suspension — preserving adaptive damping and driver assistance features. The result is a more responsive, planted driving feel with a sharper look and optimized performance.
