BC Racing RM Series Coilover System (2008 - 2014 Subaru Impreza STI Hatchback GRB) - F-10-RM
Inverted Coilover Strength for the GRB STI Hatch
Give your 2008 - 2014 Subaru Impreza STI Hatchback (GRB) the suspension performance it deserves with the BC Racing RM Series Coilover System. Engineered specifically for MacPherson-style strut platforms, the RM Series features BC's premium inverted mono-tube damper design, which relocates the heaviest portion of the strut toward the chassis to significantly reduce unsprung weight. The result? Sharper response, improved stability, and enhanced chassis control - ideal for a high-performance AWD platform like the GRB STI.
At the heart of the RM Series is a large-diameter inverted piston shaft designed to withstand the high lateral loads that naturally occur during aggressive cornering, canyon runs, and track use. With independent ride height adjustment, 30-way damping control, and fully rebuildable internals, the RM Series is the perfect blend of strength, tunability, and long-term performance.
Performance Highlights
- Inverted mono-tube damper design reduces unsprung mass and increases rigidity under load.
- Large inverted piston shaft resists fatigue during high lateral G-forces.
- Linear damping curve provides stable, predictable handling.
- 30-way adjustable compression/rebound for fine tuning street, track, or canyon setups.
