The BC Racing BR Series RS Coilovers deliver precision suspension tuning for the BMW M5 RWD F10 (12-16), engineered with a 10/6kg.mm spring rate to enhance both road handling and track performance. Featuring rubber top mounts on both front and rear, these coilovers provide a balanced setup that maintains comfort whilst offering responsive control for demanding driving conditions. Whether optimising your M5 for daily driving or circuit use, the BC Racing BR Series RS offers the adjustability and quality construction expected from a leading performance suspension solution.
The BC Racing BR Series offers entry into coilover suspension without sacrificing performance, comfort, build quality or handling. Each kit is developed through extensive vehicle-specific testing and refinement, ensuring the most well-balanced and affordable aftermarket suspension possible for each application. The BR series coilovers use a large 46mm diameter piston in a 53mm diameter damper body — as the damper operates, oil temperature rises and viscosity changes, which can alter damping characteristics. The enlarged 53mm body increases oil capacity, reducing the peak temperature and maintaining more consistent damping performance as a result.
A single adjuster controls both compression and rebound simultaneously, giving a wide tuning range without the complexity of separate circuits. The balance between front and rear axles can be shifted to influence handling — the effect is repeatable and noticeable across the 30 positions of adjustment.
Ride height is set via the bottom mount rather than the spring platform, meaning full damper travel is retained at any ride height chosen. The tapered bottom mount locking collar locks the setting securely without requiring tools to recheck after every session.
The RS configuration is supplied with aluminium front top mounts with rubber centres and aluminium rear top mounts with rubber centres, or no rear top mounts depending on the application.
