BC Racing ER Series Coilovers for 2014-2015 Bmw M3/M4 RWD (F80/82)

BC Racing ER Series Coilovers for the 2014-2015 Bmw M3/M4 RWD (F80/82) represent BC Racing's dedicated track and motorsport platform — featuring independent 30-level compression and 30-level rebound adjustment for complete control over suspension behavior. Unlike the BR and DS Series where compression and rebound are adjusted simultaneously, the ER Series lets you dial each independently, giving experienced drivers and track-day enthusiasts the ability to fine-tune the suspension response for specific conditions.
