BC Racing RM Series Coilover System (1990 - 1994 Subaru Legacy BC / BJ / BF) - F-18-RM
Inverted Coilover Upgrade for the First-Gen Legacy
Give your classic 1990 - 1994 Subaru Legacy BC/BJ/BF a modern suspension overhaul with the BC Racing RM Series Coilover System. Built specifically for vehicles using MacPherson-style OEM struts, the RM Series features BC's advanced inverted mono-tube damper design, relocating the heaviest part of the strut toward the chassis. This reduces unsprung weight, sharpens steering response, and increases chassis rigidity - an especially meaningful upgrade for early Legacy platforms now seeing restoration, spirited street use, or performance builds.
The RM Series incorporates a large-diameter inverted piston shaft engineered to handle sustained lateral loads, ensuring consistent, fatigue-resistant performance. Combined with 30-way damping adjustability, independent ride height control, and full rebuildability, this system brings modern suspension precision to a classic Subaru chassis.
