These coilovers feature fully adjustable damping and ride height, allowing you to fine-tune your M2's suspension geometry for optimal performance. BC Racing's proven ER Series technology provides the responsive control and reliability demanded by discerning BMW enthusiasts and track day drivers.
The BC Racing ER Series brings with it the high quality and unique features of the BR and DS Series, with the additional benefit of external reservoirs and the ability for the driver to individually adjust and set compression and rebound damping rates. Separating the adjustment for compression and rebound allows the car to be dialled in to exact requirements — a level of precision not available with a single combined adjuster.
Compression damping controls how the car transfers weight to its tyres during braking — allowing the front to load progressively for maximum braking grip and enabling trail braking into a corner. Rebound damping controls how the suspension responds as load is released on corner entry, keeping the front end hooked up rather than snapping back and causing understeer. Tuning each independently, without one adjustment affecting the other, is a significant advantage for circuit use — corner exit speed is ultimately determined by how well the front stays loaded through the entry phase, and that comes down to the balance between compression and rebound.
