2021 Porsche 718 Cayman GT4 DeMan 4.5L 6-Speed

This 2021 Porsche 718 Cayman GT4 is powered by a flat-six that was modified in 2022 with a 4.5-liter conversion by DeMan Motorsport, who also fitted catalyst-equipped headers, over-axle exhaust pipes, a lightweight clutch and flywheel, a limited-slip differential, and revised gearing for the six-speed manual transaxle. Finished in Gentian Blue Metallic over black leather and Race-Tex, the car also has 20″ 718 Spyder alloy wheels, a rear wing, bi-xenon headlights, the Porsche Dynamic Lighting System, ParkAssist, the Chrono package, Sport Seats Plus, automatic climate control, and Porsche Communication Management. Purchased by the seller in 2025, this modified 982 718 Cayman GT4 has 29k miles and is offered in Kentucky with owner’s manuals, a DME report, service records, a clean Carfax report, and a clean Florida title in the seller’s name. The car is finished in Gentian Blue Metallic (M5D), and exterior equipment includes a rear wing, ParkAssist, and bi-xenon headlights in black with the Porsche Dynamic Lighting System (PDLS) as well as side air intakes, tinted windows, and dual exhaust outlets. Full-body paint-protection film is said to have been applied, and the seller notes scratches under the film.
