KW V3 Coilover Kit – BMW M3 (E90 / E92)

OVERVIEW

The KW Variant 3 coilover system is state-of-the-art damper technology for the skilled and experienced driver. Separate, independent compression and rebound damping adjustment allows a genuinely individual driving set-up rather than a single fixed calibration.

The system's three individually adjustable components let the driver tune low-speed compression damping on the car, while the high-speed compression behavior that governs ride comfort has been preset by KW's engineers. Height adjustment is independent of both.
