Celica GT4 ST205 BC Racing ER Coilover Suspension kit - ER Series with External Reservoir


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.

Rideheight adjustable - the lower mount can be wound up or down the damper body to allow rideheight adjustment.

The lower spring platform of the BC Racing coilovers are adjustable, to allow corner weight adjustment.
