- Product Details
The BC Racing ZR Series Coilovers bring a 3-way adjustable track ready coilover system to racers from novice to pro for an affordable price that has never been seen in the industry. Each ZR Series Coilover system offers independent low-speed/high-speed compression adjustments and separate rebound adjustment.
On cars with McPherson struts, the ZR Series comes standard with an inverted mono-tube damper. The damper has a steel braided Teflon coated line exiting the top of the damper 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. These dampers have steel braided Teflon Coated lines or solid stem that exit the damper at the bottom and lead to the external reservoir that can be mounted under the chassis or on the shock body itself. The ZR Series offers 30 clicks of rebound adjustment, 15-clicks of low speed compression adjustment and 12 clicks of high speed compression adjustment.
- Inverted monotube damper with twin piston design
- Height adjustment via the shock body, not the spring
- 30 levels of independently adjustable rebound
- 15 levels of independently adjustable low-speed compression

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. Some vehicles reuse OEM upper mounts
