BC Racing DS Series Coilovers for the PONTIAC GRAND PRIX (04-08) deliver precision suspension tuning with a 5/6kg.mm spring rate, engineered for drivers seeking enhanced handling and adjustability. These premium coilovers combine adjustable damping with quality construction, making them an excellent choice for both road and track applications on your Grand Prix. Whether you're looking to improve cornering performance or fine-tune your suspension setup, the BC Racing DS Series offers the reliability and control expected from a leading performance suspension manufacturer.
BC Racing DS Series Coilovers
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.

Digressive Piston Valving
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.
