The BC Racing DS Series Coilovers for BMW 5 SERIES TOURING F11 (10-17) 10/Xkg.mm deliver premium suspension performance for drivers seeking precision handling and adjustability on UK roads. These coilovers feature the BC Racing DS Series' renowned quality construction, engineered to enhance your touring estate's dynamic capabilities with their 10/Xkg.mm spring rate specification. Whether you're looking to refine your F11's stance or improve its cornering response, this suspension solution provides the control and reliability expected from a leading performance car parts choice.
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.
