• Arms and bushings: HARDRACE caster, lower, toe and camber arms, and SPL trailing arms, dogbone links and subframe bushings.
• Links: SPL, HARDRACE and Torque Solution adjustable end links.

• 4S or Carrera 4: the 4S has larger brakes. Choose big brake kits titled C2S / C4S, not the C2 / C4 kits.
• All-wheel drive coilovers: pick kits listed for the Carrera 4 / 4S, not the rear-drive Carrera 2.
• Coupe or Cabriolet: EDC cancellation kits differ by body style, so check the title.

Suspension arms, coilovers and brakes should be fitted by a qualified workshop, followed by a wheel alignment and a brake bleed and road test. A limited slip differential is a gearbox job for a Porsche specialist. Always follow the maker's instructions and torque settings.
