BC Racing ZR-Series Coilovers | 2000-2006 BMW M3 Convertible (I-121-ZR)

ZR-Series Coilovers for 2000-2006 BMW E46 M3 Convertible by BC Racing 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.
