2020 Porsche 718 Cayman GT4 – 6-Speed Manual, Carbon Buckets, Miami Blue, 8k Miles
This 2020 Porsche 718 Cayman GT4 is finished in Miami Blue over a black leather and Alcantara interior and shows just 8,000 miles. Power comes from a naturally aspirated 4.0-liter flat-six mated to a six-speed manual transaxle and a limited-slip differential with Porsche Torque Vectoring. The seller purchased the car in 2022 and has added approximately 4,000 miles under their ownership.
Factory and performance equipment includes carbon-fiber full bucket seats, the Sport Chrono Package, carbon-fiber interior trim, Bose audio, 20″ Cayman GT4 wheels, and bi-xenon headlights. Modifications consist of a yellow-finished roll cage, Tarett Engineering rear toe links, SPL Parts front caster arms, EdGuard seat bolster protectors, and recent ceramic coating applications. This GT4 is now offered with its window sticker, DME report, Porsche inspection documentation, service records, a clean Carfax, and a clean California title in the seller’s name.
Exterior
The car is finished in striking Miami Blue and features a fixed rear wing, rear ParkAssist, bi-xenon headlights, side air intakes, and center-exit dual exhaust outlets. Paint protection film is applied to the front fascia, mirror caps, rocker panels, and side intakes, and the seller reports that multiple layers of ceramic coating have been applied, including a final treatment ahead of the sale. The windshield was replaced in April 2025 by Porsche of Irvine.
The 20″ GT4-specific wheels are finished in silver and mounted with Dunlop high-performance tires. Yellow-painted calipers clamp ventilated and dimpled rotors, and the braking system received a fluid flush in June 2024. Suspension upgrades include Tarett Engineering rear toe links and SPL Parts front caster arms.
