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 20-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.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eOn cars with McPherson struts, the ZR Series comes standard with an inverted mono-tube damper.
