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.\u003c\/p\u003e\n\u003cp\u003eHM Series kits use an inverted mono-tube damper on McPherson-strut chassis (upright on double-wishbone) with external reservoirs feeding separate compression and rebound adjusters. The result: the tuning depth of the ER Series inside the heavy-load chassis architecture of the RM. Where BC Racing separates itself is tuning philosophy: every off-the-shelf spring rate and damper setup is chosen to stay comfortable on daily roads while still delivering real performance at the track. If you want something different, Swift Springs, custom rates, and custom valving are all options at checkout — BC will match the valving of the dampers to whatever springs you pick, something most brands don't offer outside their flagship race lineup.\u003c\/p\u003e\n\u003cp\u003eSince 2004, BC Racing has grown into one of the most trusted names in aftermarket coilovers — not by racing to the bottom on price, but by pairing that price with real build quality, deep customization options, and a damper design any suspension shop can rebuild instead of replacing. These WRX STI Hatchback coilovers arrive tuned for the GRB chassis and ready to bolt in — no break-in period, no guessing at setup. \u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e30-level rebound adjustment (top of damper)\u003c\/li\u003e\n\u003cli\u003e30-level compression adjustment (external reservoir)\u003c\/li\u003e\n\u003cli\u003eInverted mono-tube damper on McPherson-strut vehicles; upright on double-wishbone\u003c\/li\u003e\n\u003cli\u003eCombines RM Series inverted-damper architecture with ER Series 2-way adjustability\u003c\/li\u003e\n\u003cli\u003eRide height adjustable independent of spring preload\u003c\/li\u003e\n\u003cli\u003eUpper mount hardware varies by chassis — camber plates, pillowball, or reused OEM mounts.
