BC Racing ZR Series

The BC Racing ZR Series coilovers offer the most adjustability of any BC coilover system to date. Each ZR Series system is track tested and developed specifically for racers looking for more damping adjustability than the ER or HM Series can provide. It offers 20 clicks of low-speed compression adjustment, 12 clicks of high-speed compression adjustment and 30 clicks of rebound adjustment, along with full height adjustability independent of piston shaft travel and spring compression.

On cars with McPherson struts, the ZR Series comes standard with an inverted mono-tube damper. A steel braided line exits the top of the damper and leads to external reservoirs that can be remotely mounted on the chassis for easy adjustment. Cars with double A-arm suspension come with upright dampers, which have steel braided lines or solid stems exiting at the bottom and leading to an external reservoir that can be mounted under the chassis or on the shock body itself.
