The BC Racing RM Series Coilover System is for McPherson style OEM strut suspension using a mono-tube inverted damper in the front and rear. BC Racing provides an inverted front strut, On vehicles that use front struts only, with an upright BR Series damper in the rear. Inverted dampers decrease unsprung weight by moving most of the strut mass where weight can be more easily shaved, the top, where it connects to the sprung weight of the chassis. A much larger inverted piston shaft that can handle higher lateral loads for longer periods of time without fatigue is used in the RM Series Coilover System.
