BC Racing RM Series Coilover System (2015 - 2021 Subaru Impreza STI / WRX VAB / VAF / VAG) - F-25-RM
Inverted Coilover Performance for WRX & STI (VAB / VAF / VAG)
Unlock sharper steering response, improved chassis rigidity, and race-ready suspension control for your 2015 - 2021 Subaru WRX or STI with the BC Racing RM Series Coilover System. Designed specifically for MacPherson-strut Subaru platforms, the RM Series features BC's proven inverted mono-tube damper design, which relocates the damper's mass upward to reduce unsprung weight and enhance reaction time.
Built with a large-diameter inverted piston shaft, this system withstands extreme lateral loads commonly experienced in performance AWD chassis like the VAB/VAF/VAG platform. Whether your WRX/STI is street-driven, track-focused, or autocross-tuned, the RM Series delivers consistent damping, independent ride height adjustment, and long-term durability.
