The BC Racing ER Type Coilovers are the next phase in ultra high performance coilover systems.  ER Type, or “External Reservoir” coilovers are the newest and most advanced model yet and feature large external reservoirs front and rear, separate rebound and compression adjustment and a twin-piston design. The external reservoirs hold much more oil than conventional coilovers, allowing the unit to operate for much longer before overheating. Additionally, the external reservoirs also house the secondary piston, which allows for the adjustment of compression. This is the perfect coilover system for the person who wants to fine-tune their setup using the separate 30-way rebound and compression tuning dials.

– Full height adjustability through shock body not spring
– 30 levels of dampening adjustment Rebound is on top of the shock, compression is on the reservoir
– Adjustable rear camber plates on certain applications only
– 1 Year warranty against manufacturer defect
