BC Racing ZR Series Coilovers
BC Racing's ZR Series brings a 3-way adjustable track-ready coilover system to racers from novice to professional at a price not previously seen in the performance suspension market. Each ZR system offers independent low-speed and high-speed compression adjustment and separate rebound adjustment, with full height adjustability independent of both piston travel and spring preload. On MacPherson strut applications, the ZR uses an inverted monotube damper with a Teflon-coated steel braided line from the top of the damper to external reservoirs that can be remotely mounted in the engine bay or boot.
