The ER series is BC Racing’s latest and most advanced model on the market. Featuring large external reservoirs both front and rear, it has separate rebound & compression adjustment as well as a twin-piston design. External reservoirs hold substantially more oil than conventional coilovers and this ability to store extra shock fluid helps resist high temperatures created by prolonged track use and permit longer periods of operation before overheating. These external reservoirs house the secondary piston, which allows for the adjustment of compression. This is the ideal suspension/damper system for the tuner who wants to precisely dial in their setup. Every lower mount is designed with the OEM piece at hand to ensure an exacting fit and perfect manufacturer tolerance specifications.
