BC RACING – ADJUSTABLE COILOVER ER BMW SERIES 3 F30 RWD

BC Racing’s flagship premium coilovers are the ER Series external reservoir coilovers with separate compression and rebound damping adjustment. ER Series coilovers retain 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 external reservoir coilovers allow BC Racing to increase the shock absorber’s oil capacity. The additional oil capacity reduces peak oil temperatures, which decreases damping rate variations due to oil viscosity variations. Reducing damping rate variations improves handling and maximum performance on the street and track.
