BC Racing ER Series

The BC Racing ER Series coilover system is the next evolution in suspension tuning and vehicle setup. It offers 30 clicks of independently adjustable compression and rebound, with remote reservoirs that increase oil capacity and help with faster heat dissipation.

Each ER Series system undergoes the same rigorous testing and development as the coilover series that precede it, with the addition of more extensive real-world track testing. For racers and enthusiasts looking for more adjustability across compression and rebound settings, look no further.

Before you order

An optional check valve keeps rebound and compression adjustments separate, reducing oil flow interference. This allows for more accurate tuning, sharper handling and improved performance under aggressive driving, but may not be ideal for those who prioritise ride comfort.

Noise from track-oriented products such as the DS, RM, ER, HM, ZR or ZX coilovers is not covered by warranty.
