Subaru Impreza WRX (GC) 1994–2000 Performance Parts & Upgrades

The first Subaru Impreza WRX was sold new in Australia from 1994 to 2000 as the GC sedan and GF hatch, and many more reached Australia as Japanese imports. It uses the 2.0L EJ20 turbo flat-four with all-wheel drive. Many chassis parts carry over to the GD WRX that followed. This page lists the parts we stock for the GC WRX, from HARDRACE arms, sway bars and bushings to GFB blow-off valves and shifters, GrimmSpeed and Got It Rex parts, GSC Power-Division and Manley engine parts and Drive Shaft Shop axles.

Popular upgrades for the GC WRX
  • Suspension: HARDRACE sway bars, camber, toe and caster arms, stabiliser links and hardened strut mounts.
  • Bushings and mounts: HARDRACE control arm bushes and engine mounts to refresh a tired chassis.
  • Turbo and boost: GFB blow-off valves and wastegate actuators, Turbosmart parts and GrimmSpeed heat shields.
  • Engine: GSC Power-Division valvetrain and camshafts, Supertech valves, Manley and Nitto rods, ACL and King bearings and ARP case bolts for EJ20 builds.
  • Driveline and cooling: Drive Shaft Shop axles and carbon driveshafts, GFB short shifters, and Got It Rex radiator hoses and cooling plates, and a Perrin coolant tank.
  • Brakes: Alcon, AP Racing, Brembo and Paragon big brake kits and Paragon rear rotors.
Choosing the Right Part
  • AU-delivered or JDM import: Japanese cars and STI versions can differ in turbo, intercooler and brake setup. Check what your car has before ordering.
  • Model year: some parts, such as GFB blow-off valves, are made for certain model years only. Check the years in the title.
  • GC or GD: many HARDRACE parts fit both, but some suit the GC only. Check the chassis codes in the title.
  • Age and past repairs: most GC WRXs have had parts changed by earlier owners. Check what's fitted before you order.
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. Boost and engine changes need a tune to suit.
