Porsche 718 Cayman GT4 982 Performance Parts & Upgrades

The Porsche 718 Cayman GT4 (982) arrived in Australia in 2019 as the track-focused Cayman. It uses a naturally aspirated 4.0L flat-six behind the seats, rear-wheel drive and its own suspension, brakes and aero. This page lists the parts we stock for the GT4, including Paragon 2-piece rotors, MOTON coilovers, Suspension Secrets camber plates, SPL and HARDRACE arms and links, APR Performance carbon canards and Gurney flap, COBB Accessports, a Wavetrac manual diff and Frenkit caliper seal kits.

Popular upgrades for the GT4
  • Suspension: MOTON coilovers made for the GT4, Suspension Secrets Stage 1 and Stage 2 rear camber plates, and the Öhlins EDC cancellation kit.
  • Arms and links: SPL rear traction arms and front end links, HARDRACE stabiliser links and rear toe kits, and Torque Solution drop links.
  • Brakes: Paragon 2-piece front (380 x 34mm) and rear (380 x 30mm) rotors and Frenkit rear caliper seal rebuild kits.
  • Aero: APR Performance carbon fibre canards and Gurney flap.
  • Tuning and drivetrain: COBB Accessport V3 for the GT4 with or without PDK flashing, and a Wavetrac limited slip diff for the 6-speed manual.
Choosing the Right Part
  • GT4 or base Cayman: the GT4's suspension and brakes are different from the regular 718 Cayman. Buy parts that name the GT4.
  • GT4 or GT4 RS: some Suspension Secrets top mounts are made for the RS only. Check the title before ordering.
  • Ceramic brakes: the Paragon rotors replace steel discs. Cars with optional ceramic brakes (PCCB) need different parts.
  • Manual or PDK: the Wavetrac diff here suits the 6-speed manual, and the Accessport comes with or without PDK flashing.
Installation

Suspension and brake work on these cars should be done by a qualified workshop. Book a wheel alignment, ideally a corner-weighted track setup, after fitting camber plates, arms or links, and bleed and road-test the brakes after any brake work.
