BC Racing""s flagship premium coilovers are the ER series with external reservoir with separate compression and rebound damping adjustment. ER Series coilovers bring with them the high quality and unique features seen on the BR and RM types, but have the added benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates.
ER series coilovers with external reservoir allow BC Racing to increase shock oil capacity. The additional oil capacity reduces peak oil temperatures, decreasing changes in damping rates due to changes in oil viscosity. Reducing damping rate variations improves handling and maximum performance on the road and track.
