KW Height Adjustable Spring (H.A.S.) kit for the 2008-2013 BMW M3 (E90 sedan/E92 coupe/E93) and 1 Series M. 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 dampers and wheel loads, and vehicle-specific bump stops with a dust-protection system are included.
