BC Racing ER Type Coilovers Subaru Impreza STI 2008-2010 | F-10-ER

Our newest and most advanced model yet is the ER Type coilover system. 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 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.
