KW Suspensions H.A.S. Height Adjustable Lowering Springs - BMW F80 M3 / F82 M4

The F80 M3 and F82 M4 are already purposeful machines. The factory ride height is the one thing that softens the visual impact: more gap in the fenders than these platforms deserve. The KW H.A.S. closes that gap without requiring you to change your shocks.

This is a spring-only upgrade. The H.A.S. system replaces your factory springs with KW units that include an adjustable spring perch. You set your target ride height within the lowering range at installation, so you are not locked into a single fixed drop the way you would be with standard lowering springs. Your OEM dampers stay in place, maintaining the suspension character BMW tuned into the F80 and F82 platforms.
