A DeMan Motorsport 4.5-liter engine powers this 2020 Porsche 718 Cayman GT4, and a replacement six-speed manual transaxle fitted with a close-ratio gearset. The factory engine was removed, bored over, and stroked as part of the project, which also involved the installation of a revised limited-slip differential, flywheel, clutch assembly, headers, and exhaust piping. Suspension; JRZ adjustable coil overs featuring external reservoirs, monoball camber plates, and Tarret Engineering toe arms. Dundon Motorsport canards have been added to the front bumper, while a DeMan Motorsport roll bar and Schroth harnesses have been added inside the cabin. Finished in Chalk over black leather and Alcantara upholstery, the car left the factory equipped with 20″ wheels, carbon-ceramic disc brakes, carbon-fiber full bucket seats, a Bose surround-sound system, navigation, and LED headlights with PDLS+. This modified 718 GT4 has 30k miles and is now offered with a window sticker, manufacturer’s literature, service records, a clean Carfax report, and a clean Nevada title.
Factory-finished in Chalk, the car is equipped with a front splitter, a fixed rear wing, a rear diffuser, side air intakes, and LED headlights with the Porsche Dynamic Light System Plus (PDLS+). Front canards from Dundon Motorsport have been added, and the seller states that paint protection film has been applied to the bodywork.
Staggered-width 20″ wheels are wrapped with 245/35 front and 275/30 rear Michelin Pilot Sport Cup 2 tires that were mounted in November 2023. Stopping power is provided by black-finished brake calipers over carbon ceramic rotors at each corner. Installed in October 2022, the car rides on JRZ adjustable coilovers with external reservoirs and has been fitted with monoball camber plates and Tarret Engineering toe arms.
The cabin houses carbon-fiber full bucket seats trimmed in black leather and Alcantara with Chalk stitching, seatbelts, trim, and fabric door pulls. The car has been fitted with Schroth harnesses and a DeMan Motorsport roll bar as well as an AIM SmartyCam 3 and a SOLO 2 DL to record and monitor vehicle performance. Additional amenities include automatic climate control, cruise control, a Bose surround sound system, and Porsche Communication Management with navigation.
The three-spoke steering wheel frames a tachometer with an 8k-rpm redline accompanied by a 200-mph speedometer, both of which have white dials. A TFT LCD screen to the right features auxiliary readouts for fuel level, coolant temperature, oil temperature, and oil pressure. The digital odometer indicates 21k miles, all of which have been added under current ownership.
The factory 4.0-liter flat-six was removed, bored over, and stroked by DeMan Motorsport in January 2022. Now displacing 4.5 liters, the engine runs on 91 octane and is fitted with a Porsche 991 crankshaft, Carrillo connecting rods, and Mahle racing pistons.
Power is sent to the rear wheels through a replacement six-speed GT4 transaxle with shortened gear ratios and a DeMan Motorsport limited-slip differential. The unit was installed in January 2022 along with a revised flywheel, clutch assembly, and shifter cables. The exhaust system features DeMan Motorsport headers and over-axle piping.
