• Track suspension: Suspension Secrets camber caster plates, camber shim kits, monoball and solid control arm bushes and bump steer tie rod ends, plus MOTON coilovers and the Öhlins EDC cancellation kit.
• Brakes: Paragon 2-piece front and rear rotors for the iron brakes, and Frenkit rear caliper rebuild kits.
• Drivetrain and engine: a Wavetrac PDK limited slip diff and GSC Power-Division valve springs with titanium retainers.
• Cockpit and tuning: the KMP Clubsport steering wheel and the COBB Accessport V3 for the GT3 and GT3 RS.

• GT3 or Carrera: GT3 suspension, brakes and aero differ from the Carrera, so choose parts that name the GT3. Carrera-only parts won't fit.
• Iron or ceramic brakes: the Paragon rotors are for cars with iron brakes. Check whether your car has ceramic (PCCB) brakes first.
• 991.1 or 991.2 aero: some APR Performance parts are 991.1 GT3 only and others fit both. Check the code in the title.

Have a qualified workshop fit suspension, brake and aero parts. Monoball and camber changes need a full alignment, ideally a track setup. Valve spring and diff work is a specialist engine and gearbox job.
