The BC Racing DS Series coilovers for BMW 3 SERIES (W/O EDC) COUPE E92(M3) (08-13) deliver precision handling and adjustable suspension geometry specifically engineered for your E92 platform. These performance coilovers feature a 6/10kg.mm spring rate designed to balance responsive cornering with daily usability, making them an ideal choice for enthusiasts seeking professional-grade suspension performance. With full height and damper adjustability, the BC Racing DS Series enables you to fine-tune your BMW's stance and suspension characteristics to suit your driving style and road conditions.
The BC Racing DS Coilover system is built with digressive valving, offering the same great benefits of the BR Series and is considered a perfect choice for those looking for track-biased coilovers. The digressive piston design produces a non-linear damping curve — allowing higher low-speed damping to control body roll through cornering, acceleration and braking, while providing reduced high-speed damping to allow the wheel to travel when running kerbs, preventing the impact from transmitting fully into the shell and retaining car balance.
Unlike a conventional linear piston, the DS digressive design increases damping force at low piston velocities — the range associated with body roll, pitch and dive during driven inputs — while reducing damping force at high piston velocities, such as when a wheel travels over a kerb. This keeps the car stable during cornering loads while allowing impacts to be absorbed without upsetting the chassis balance.
