Ohlins Dedicated Track coilover system for the 2000-2006 BMW M3 (E46). Uses the same Dual Flow Valve (DFV) monotube architecture as the Road & Track line but tuned for circuit use only — featuring spherical upper mounts for precise camber response, stiffer application-specific spring rates (120 N/mm front / 160 N/mm rear, Swift springs built to Ohlins spec), and 20-click adjustable damping. Ride height adjustable; target lowering approximately 20mm. System is fully rebuildable.
