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. On cars with McPherson struts, the ZR Series comes standard with an inverted mono-tube damper. 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. These dampers have steel braided lines or solid stems 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.

Adjustment that stays usable

Ride height is set independently of spring compression, so lowering the car does not preload the spring or cost you travel. Damping is a single 30-click sweep moving compression and rebound together — one adjustment per corner, easy to repeat and easy to undo.

Built to be serviced, not replaced

Every kit is fully rebuildable and can be revalved, and custom spring rates — including Swift Springs — are available if your setup outgrows the off-the-shelf specification.
