BC Racing DS Series Coilovers for the Audi A4 AVANT (Strut 53) FWD B9 (2016+) deliver precision handling and adjustable suspension geometry with a 10/0.5kg.mm spring rate configuration. These performance-engineered coilovers provide independent front and rear tuning capabilities, allowing drivers to fine-tune their suspension setup for both road and track applications. Built to exacting standards, the BC Racing DS Series offers the responsive control and lowering potential that serious enthusiasts demand from their A4 AVANT.
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.
