Öhlins Road & Track DFV Coilover Kit – BMW M3 (E90 / E92 / E93)

OVERVIEW

Öhlins Road & Track is a DFV (Dual Flow Valve) monotube coilover system built for street driving with a real track-day edge. Öhlins' patented DFV valving separates high- and low-speed damping forces so the car stays compliant over broken pavement while still controlling body motion hard on track. One adjuster per damper changes compression and rebound together, so there is no guesswork tuning the two independently.

Öhlins part number BMS MI40S1 is the dedicated Road & Track kit for the BMW M3 (E90 / E92 / E93), with its own spring rates, ride-height range and mounting hardware. It reuses the factory top mounts, is rebuildable, and carries Öhlins' 2-year limited warranty.
