BC Racing's new ZR Series Coilovers are bringing a 3-way adjustable track ready coilover system to racers from novice to pro for an affordable price thates never been seen in the industry. Each ZR Series Coilover system offers independent low speed/high speed compression adjustments and separate rebound adjustment. They also offer full height adjustability independent of piston travel and spring preload. On cars with McPherson struts the ZR Series comes standard with an inverted mono-tube damper with the 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 with 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.
