About KW H.A.S.

H.A.S. kits use multi-coated chrome-silicon springs with rates matched to your factory dampers and wheel loads, plus application-specific bump stops with dust protection where applicable. KW says the factory electronic or adaptive suspension functions stay operational, and ride height is adjustable at each corner.

KW develops vehicle-specific spring rates and parameters on the Nürburgring Nordschleife and in its own 7-post test center.
