The E60 M5 and E63 M6 have a presence that stock ride height undercuts. You have a 500-horsepower V10 sedan or grand touring coupe sitting too tall, and all you need are better springs.

The KW H.A.S. is a spring kit, not a coilover. Your factory dampers stay exactly where they are. The H.A.S. system replaces the springs with KW units built around an adjustable spring perch — that adjustability is what makes this different from standard lowering springs. You choose your final ride height within the available range at installation rather than accepting a fixed drop. The ride character the E60 M5 and E63 M6 were built to deliver stays intact.
