BC Racing RM Series Coilover System (2014 - 2018 Subaru Forester SJ) - F-23-RM
Inverted Coilover Performance for the Forester SJ
Elevate the handling and confidence of your 2014 - 2018 Subaru Forester SJ with the BC Racing RM Series Coilover System. Built for vehicles using MacPherson-style strut suspension, the RM Series incorporates BC Racing's advanced inverted mono-tube damper design, shifting the damper's heaviest mass upward toward the chassis. This dramatically reduces unsprung weight, increases rigidity, and sharpens suspension response - an ideal upgrade for the taller AWD Forester platform.
A large-diameter inverted piston shaft provides exceptional durability under high lateral loads, making the RM Series perfect for spirited driving, lifted adventure builds, or street performance. With 30 levels of damping adjustability, independent ride height control, and fully rebuildable construction, this system delivers tuning flexibility and long-term reliability for any Forester SJ setup.
