BC Racing DS Series Coilovers 2015-2021 Impreza STI / WRX (VAB / VAF / VAG)

BC Racing DS Series Coilovers for the 2015-2021 Subaru WRX STI (VA2) blend street-tuned ride quality with track-ready adjustability, giving you more body control than any OEM damper without the harshness of a pure race kit. Every kit is extensively tested on the WRX STI VA2 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.

DS Series kits pair a mono-tube damper with BC's proprietary digressive piston design — increased low-speed damping for flat corner entry, compliant high-speed response over expansion joints and potholes. The finished shock body is silver, visually distinct from the BR Series, and ride height is adjustable independent of spring preload. 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.

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 VA2 chassis and ready to bolt in — no break-in period, no guessing at setup.
