Every kit is extensively tested on the WRX STI Sedan chassis and refined until it balances ride quality with performance — the reason WRX STI Sedan coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.\u003c\/p\u003e\n\u003cp\u003eER Series kits run a linear twin-piston design in a mono-tube body, with compression and rebound on separate external adjusters. That lets you fine-tune chassis balance corner by corner — stiffer front for turn-in, softer rear for exit grip, whatever the session calls for. 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.\u003c\/p\u003e\n\u003cp\u003eBC Racing's reputation in the aftermarket suspension world is built on four things: competitive pricing that beats the rest of the fully-adjustable market, customization depth that rivals the top-tier race brands, long-term reliability earned over 20 years of production, and a rebuildable design that keeps the same set of dampers serving you through multiple builds. These WRX STI Sedan coilovers arrive tuned for the WRX STI Sedan 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\u003eMono-tube damper with linear twin-piston design\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.
