BC Racing RM Series Coilover System (2012 - 2014 Subaru Impreza WRX Sedan GJ7 / 2012 - 2016 Subaru Impreza G4 Sedan Base GJ / GP) - F-21-RM
Inverted Coilover Performance for the GJ7 WRX & G4 Impreza Sedan
Enhance your 2012 - 2014 Subaru Impreza WRX Sedan (GJ7) or 2012 - 2016 Subaru Impreza G4 Sedan / Base (GJ / GP) with the BC Racing RM Series Coilover System. Engineered specifically for MacPherson-style strut suspension, the RM Series uses BC's high-strength inverted mono-tube damper design. This shifts the damper's heaviest mass upward toward the chassis, reducing unsprung weight and improving suspension response, steering feel, and overall stability.
The RM Series features a large-diameter inverted piston shaft capable of handling extended lateral loads - ideal for spirited driving, back-road performance, and drivers who demand sharper control. With independent height adjustment, 30-click damping control, and fully rebuildable construction, the RM Series offers both reliability and precision setup flexibility for WRX and Impreza G4 sedan owners.
