The BC Racing DS Series coilovers for the Audi A3 SEDAN (strut 54.5mm) 8V (13-20) deliver precision suspension tuning with a 6/5kg.mm spring rate engineered for responsive handling and daily driving comfort. These adjustable coilovers combine height and damping customisation to give drivers complete control over their vehicle's stance and performance characteristics. BC Racing's DS Series represents a proven solution for A3 sedan owners seeking reliable suspension upgrades backed by established tuning credentials.
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.
