Coil over suspension is the ultimate expression of high-performance handling, and now H&R Special Springs takes this technology to the next level with its new PCS Coil Overs. Like H&R's original Coil-Overs, PCS Coil-Overs are engineered for street use, but have a number of new features designed for the enthusiast who desires a manual shock dampening feature. In addition to state-of-the-art inverted damper technology and adjustable ride height, PCS Coil Overs feature an external adjustment knob that allows the user to simultaneously adjust rebound and compression. Nose-diving under hard braking is virtually eliminated, which effectively reduces braking distance. And unlike traditional twin-tube shock absorbers, H&R's mono-tube gas shock absorbers eliminate foaming of the damper oil, even under extreme conditions.
Fits all M3 E46 cars, including Convertible. Lowers car 1.0-1.9” front, 0.75-1.5” rear.
