KW Height Adjustable Spring (H.A.S.) kit for the 2021-2026 BMW M3/M4 (G80/G82) and M2 (G87). Unlike fixed lowering springs, the H.A.S. system lets you adjust ride height at each corner with millimeter precision even after installation, for a more dynamic stance and sharper steering response. Chrome-silicon steel springs are tuned to the factory adaptive dampers and wheel loads so all electronic suspension and driver-assist features stay fully operational, and vehicle-specific bump stops with a dust-protection system are included.
