BC Racing RM Series Coilover System (2011 - 2014 Subaru Impreza STI Sedan GVB / GVF) - F-17-RM
Inverted Coilover Performance for the GVB / GVF STI Sedan
Unleash sharper handling, improved chassis rigidity, and stronger lateral load support in your 2011 - 2014 Subaru Impreza STI Sedan (GVB / GVF) with the BC Racing RM Series Coilover System. Designed for MacPherson-style strut suspension, the RM Series uses BC Racing's premium inverted mono-tube damper design, which relocates the heaviest mass of the damper toward the chassis. This significantly reduces unsprung weight, increases structural rigidity, and enhances high-speed stability - perfect for the STI platform.
Featuring a large-diameter inverted piston shaft engineered to withstand intense lateral loads, the RM Series delivers exceptional performance during aggressive cornering, spirited street driving, and track sessions. With 30-way damping control, fully independent ride-height adjustment, and rebuildable construction, this system gives STI owners the flexibility and long-term reliability they demand.
