BC Racing RM Series Coilovers 2008-2014 Impreza STI Hatchback (GRB)

BC Racing RM Series Coilovers for the 2008-2014 Subaru WRX STI Hatchback (GRB) are purpose-built for McPherson-strut cars that see serious track time, with an inverted mono-tube damper engineered to outlast a hard season of lateral loads. Every kit is extensively tested on the WRX STI Hatchback GRB chassis and refined until it balances ride quality with performance — the reason WRX STI Hatchback coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

The RM Series inverts the mono-tube damper on strut-equipped chassis, putting the heavy internals where the lateral loads are worst. A wider piston shaft than conventional uprights means more consistent damping on long sessions and more fatigue life before rebuild. The off-the-shelf setup from BC Racing is deliberately balanced — spring rates and valving chosen so the kit feels comfortable day-to-day without giving up performance when you push it. Drivers who want a different recipe can spec Swift Springs, custom spring rates, or fully custom valving at checkout; BC will tune the dampers to match, which is a depth of customization most brands only offer on their top-tier kits.

BC Racing has been manufacturing adjustable coilovers since 2004 and is one of the most popular coilover brands in the automotive tuning industry for a reason: competitive pricing, deep customization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These WRX STI Hatchback coilovers arrive tuned for the GRB chassis and ready to bolt in — no break-in period, no guessing at setup.
