Subaru Impreza WRX STI (GR) 2008–2014 Performance Parts & Upgrades

The Subaru Impreza WRX STI hatch (GR) was sold new in Australia from 2008 to 2014, with the 2.5L EJ257 turbo flat-four and all-wheel drive. It shares its platform with the GV STI sedan and the GH WRX, so many parts fit all three. This page lists the parts we stock for the GR STI, from the COBB Accessport, intakes and intercoolers, KORSH and COBB exhausts and Perrin and GrimmSpeed parts to HARDRACE suspension, Paragon, Alcon and Brembo brakes and GSC Power-Division and Manley engine parts.

Popular upgrades for the GR STI
  • Tuning and intake: the COBB Accessport V3 (Australian spec), COBB MAP and flex fuel sensors, and COBB, Perrin, Process West and aFe intakes.
  • Turbo and exhaust: COBB, Perrin and Process West intercoolers, Turbosmart and GFB blow-off valves, and KORSH, COBB, Borla, REMARK and Tomei exhausts.
  • Suspension: HARDRACE and COBB sway bars, end links, toe arms and bushings, plus Perrin and COBB driveline and transmission mount bushings.
  • Shifters: COBB drivetrain packages and GFB, Perrin and GrimmSpeed short shifters and bushings.
  • Brakes: Paragon, Alcon, Brembo and AP Racing big brake kits and Frenkit caliper rebuild kits.
  • Engine and fuel: GSC Power-Division and Supertech valvetrain, Manley rods and pistons, and COBB and Radium fuel rails and lines.
Choosing the Right Part
  • Hatch or sedan: the GR hatch and GV sedan share most parts, but aero and some exhaust parts differ. Check the chassis code in the title.
  • STI or WRX: the STI has a different engine and gearbox to the GH WRX, so engine, turbo and driveline parts may not swap between them.
  • Model year: some aero parts are made for 2008-2010 or 2011-2014 cars only. Check the years in the title.
Installation

Have a qualified workshop fit suspension, brake, engine and driveline parts. Get a wheel alignment after any suspension change, and bleed and road-test the brakes after brake work. Intake, exhaust, fuel and boost upgrades need a tune.
