KW Height Adjustable Spring Kit - Audi A5/S5 2018-2025 (B9) with EDC

KW Height Adjustable Spring (H.A.S.) kit for the 2018-2025 Audi A5/S5 (B9) with EDC. 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.
