The BC Racing ER-Series is a 2-way damping adjustable coilover featuring external reservoirs front and rear. Separate compression and rebound adjustment combined with the increased oil and gas capacity of the external reservoir delivers consistent, fade-free damping under the hardest track use.
The lower spring platforms are adjustable, allowing the car to be corner weighted for perfect balance and maximum tyre efficiency. The damper units are black chromed steel for superb durability even through the darkest of European winters, while aluminium components are anodised and steel lower mounts go through an electrophoretic deposition process followed by powder coating for outstanding corrosion resistance.
