BC Racings newest and most advanced model yet is the ER series coilover. It features large external reservoirs front and rear, separate rebound and compression adjustment and a twin piston design. The external reservoirs hold much more oil than the conventional coilover, allowing the coilover to operate for a much longer period of time before overheating. The external reservoirs also house the secondary piston, which allows for the fine tuning of compression. This is the perfect coilover system for the person who wants to fine tune there setup using the separate, 30-way, rebound and compression tuning dials.
