Description
Nissan Silvia 240SX S15 (99-02) BC Racing DS Series Coilovers | 6/4kg.mm
BC Racing DS Series Coilovers for the Nissan Silvia 240SX S15 (99-02) deliver track-focused suspension performance with a 6/4kg.mm spring rate configuration. These coilovers provide precise damping control and adjustable ride height, making them ideal for drivers seeking enhanced handling and cornering capability on both road and circuit applications. Built to BC Racing's renowned standards, the DS Series offers the responsive feedback and reliability demanded by Silvia enthusiasts pursuing serious performance gains.
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.
