About DS Series
The DS series coilovers use a large 46mm diameter piston in a 53mm diameter damper body to maximise oil capacity. As the damper unit operates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit.
BC Racing's DS Coilover system is built with digressive valving offering the same great benefits of the BR Type model and is considered a perfect choice for those who are looking for track biased coilovers. The digressive piston design gives a non linear damping curve which allows higher low speed damping to be run to control body roll through cornering, acceleration and braking whilst providing reduced high speed damping to allow the wheel to travel whilst running kerbs to prevent the impact from transmitting fully into the shell so retaining car balance.
BC Racing only use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their DS range with a large 53mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance.
