KW Height Adjustable Spring Kit - Audi RS3/S3 2015-2020 (8V) with EDC

KW Height Adjustable Spring (H.A.S.) kit for the 2015-2020 Audi RS3 and S3 (8V) with electronic damper control. 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.
