Product Details
These BC Racing ZR Series coilovers fit the 2008-2014 Subaru WRX STI Hatchback AWD. They deliver the deepest damping adjustability in BC Racing's lineup, with Swift Springs included standard and three axes of independent tuning for competitive track programs. 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.
ZR Series kits use an inverted mono-tube damper with a linear twin-piston design, feeding three independent adjustment circuits. Swift Springs come standard, not as an upgrade, and the kit is race-tuned out of the box. 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. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts, no unit replacement required when it's time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.
