BR Series Coilover
The BR 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 characteristics of the unit.

BC Racing only use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their BR 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.

DS Series Coilover
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 valving offers more stability and enhances cornering ability at low shaft speed which gives you a different ride from the conventional linear valving.

RM Series Coilover
The BC Racing RM series feature high quality damping adjustable monotube inverted dampers at the front or front and rear, depending on vehicle. The RM coilovers offer the majority of the features of the BR series but with the additional benefit of the inverted damper unit. Inverting the damper unit brings with it a number of advantages.
Unsprung weight is reduced by moving the oil and gas reservoir way from the hub and attaching it to the shell. Unsprung weight is vital to a cars performance as a lighter wheel and hub assembly which readily moves in response to road bumps will have more grip when tracking over an imperfect road.

ER Series Coilover
BC Racings premium flagship coilovers are the external reservoir ER Series with separate compression and rebound damping adjustment. The ER Series coilovers bring with them the high quality and unique features seen on the BR and RM type but have the additional benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates.
The external reservoir ER Series coilovers allow BC Racing to increase the oil capacity of the damper unit. The additional oil capacity reduces peak oil temperatures which decreases variations in damping rates due to oil viscosity changes. The reduction in damping rate variations improves handling and ultimate on road and track performance.
