• Drivetrain: Wavetrac limited slip differentials for the 6-speed manual and two PDK versions, plus PDK inner and outer carrier bearings.
• Brakes: Brembo GT, GT-S and Pista front kits, Paragon 6-piston front and 4-piston rear kits, Paragon 2-piece rotors, an AP Racing CP9660 kit and Frenkit caliper rebuild kits.
• Tuning: COBB Accessport V3 with or without PDK flashing, and COBB high flow air filters.
• Suspension: AST, Öhlins and MOTON coilovers, Suspension Secrets camber and caster top mounts and the Öhlins EDC cancellation kit.
• Arms and links: SPL front lower control arms, front trailing arms, rear toe and traction arms and rear lower arm kits, HARDRACE links and toe kits, and Torque Solution drop links.

• GTS or S: the GTS shares its chassis with the Boxster S, so S suspension and brake parts usually fit. Check the title lists the GTS.
• PDK diff version: the two Wavetrac PDK diffs differ by bearing journal size (91mm or 85mm). Check your gearbox before ordering.
• Manual cars: the 6-speed manual uses its own Wavetrac diff, and the Accessport has a separate PDK flashing version.
• PASM: GTS cars usually have PASM adaptive dampers, so plan for the Öhlins EDC cancellation kit when fitting coilovers.

Have a qualified workshop fit suspension, brake and engine parts. Get a wheel alignment after any suspension change and bleed and road-test the brakes after brake work. Differential and gearbox work needs a specialist; ask us if you're unsure.
