BC Racing’s ZR series for the BMW E92 3-Series RWD is an adjustable coil overs that improve handling and appearance. Whether you go for a track or street suspension height setting, you will still experience superior performance in driving.

The BC Racing ZR Series Coilovers offer the most adjustability of any BC Racing Coilover System to date. Each ZR Series Coilover System is track tested and developed specifically for racers looking for more damping adjustability than the ER or HM Series can provide.

The ZR Series offers 15-clicks of low-speed compression adjustment, 12-clicks of high-speed compression adjustment, and 30-clicks of rebound adjustment. They also offer full height adjustability independent of piston shaft travel and spring compression.

The ZR Series comes standard with an inverted mono-tube damper on cars with McPherson struts. The damper has a steel braided line exiting the top of the damper leading to the external reservoirs that can be remotely mounted on the chassis for easy adjustment. Cars with Double A-Arm suspension come with upright dampers.

*Not all vehicles allow for inverted front and rear dampers. In such cases, an upright mono-tube damper will be supplied. The braided line/hard stem for the external reservoir exits the base of the damper when not inverted. Please note that not all vehicles use camber plates in the front and/or rear. In such cases, pillowball top mounts are supplied in place of camber plates on HM & ZR Series Coilover Systems.
