BC Racing ZX Series For BMW 3-Series F31 Touring (3-Bolt Top Mounts) (True Rear Coil)

Note: These images may not represent your application

The BC Racing ZX Series offers the highest level of adjustability within the BC Racing coilover system to date. Designed specifically for racing and track use, the ZX Series features 3-way adjustable damping force, providing 20 clicks of low-speed compression, 12 clicks of high-speed compression, and 30 clicks of rebound adjustment. The ZX Series adopts an upright cylinder design, allowing for the possibility of replacing the upper mount, while combining the excellent characteristics of the DS and ER series. Coupled with ultra-high viscosity index racing shock fluid, the ZX Series can maintain outstanding performance on the track and in drifting competitions for extended periods.

*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.
