External reservoir ER Series comes with separate compression and rebound damping adjustment. The ER Series coilovers bring with them the high quality and unique features seen on the BR Series 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.

This is the kit we recommend for the best balance of performance and comfort, designed by the factory to have the best overall compromise of spring rate, ride height range, top mount design and damping rate to suit the majority of car owners.

It is more than capable of dealing with fast road and track work but also retains a high degree ride civility so the car can still be used for mundane duties and long journeys without the ride becoming tiring.

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.
