• 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.

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.
