Road & Track [DFV] Coil-Over Kit

The kit utilizes Ohlins' proprietary Dual Flow Valve (DFV) technology, which allows users to transition between street and track settings by turning a single golden knob on the damper. This adjustment simultaneously changes all four areas of damping—low and high-speed compression and rebound—providing quicker response times and better control on uneven surfaces or curbs. Technically, the system consists of a complete set of four coilovers with spring rates of 343 lb (6K) for the front and 686 lb (12K) for the rear. The dampers are height-adjustable and fully rebuildable, ensuring longevity. They are tested for corrosion resistance according to ISO 9227 standards and carry TUV approval. The product is covered by a 2-year limited warranty. Compatibility is specific to BMW M3 E90 Sedan, E92 Coupe, and E93 Convertible models produced from 2008 to 2013. If your vehicle is originally equipped with an Electronic Damper Control (EDC) system, an Ohlins EDC Cancellation Kit (part number 35020-01) is required to ensure proper operation. Professional installation by an Ohlins dealer is strongly recommended to ensure correct setup and safety.
