BC Racing ZX Series Coilovers 2005-2007 Impreza STI (GDE / GDF)

BC Racing ZX Series Coilovers for the 2005-2007 Subaru WRX STI (GDE/GDF) bring the same three-axis adjustability as the race-spec ZR Series with valving tuned for drivers who split time between street and track. Every kit is extensively tested on the WRX STI chassis and refined until it balances ride quality with performance — the reason WRX STI coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

ZX Series kits share the three-axis damper architecture of the race-spec ZR Series, tuned out of the box for drivers who want race-grade adjustability without the ride harshness on the commute home. 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.

Since 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 coilovers arrive tuned for the WRX STI chassis and ready to bolt in — no break-in period, no guessing at setup.
