This 2018 Porsche 911 GT3 Cup is powered by a naturally-aspirated 4.0-liter flat-six paired with a six-speed sequential transaxle, and the composite bodywork is finished in white. The cabin is protected by a roll cage and features a carbon-fiber racing seat, a Schroth harness, and a fire suppression system along with an LCD display and a multifunction steering wheel with paddle shifters. Additional equipment includes a removable roof section, an air jack system, and center-lock alloy wheels. A replacement chassis was installed approximately 25 hours ago, and three hours have been added since the engine was rebuilt by Porsche Motorsports in 2023. This 991.2 GT3 was acquired by the current owner in 2025 and is now offered in Texas by the selling dealer with a bill of sale.
The GT3 Cup features aluminum-steel composite bodywork, and this example is finished in white. The car was repainted at the time of the chassis replacement, and the seller tells us that approximately 25 hours have been added since the work was completed. Equipment includes a carbon fiber rear wing, a front splitter, polycarbonate side and rear windows, a rescue hatch, xenon headlights, and LED taillights. There is a crack on the front bumper, and other blemishes are shown up close in the gallery.
Silver 18” center-lock wheels were mounted with Pirelli racing slicks in preparation for the sale, and the car is equipped with an air jack system. Braking is handled by Porsche-branded calipers over slotted rotors cooled by front air deflectors and rear ducts.
The cabin houses a single fixed-back carbon-fiber bucket seat with head restraints and a Schroth Racing multi-point harness. Safety equipment includes a roll cage with door bars, a window net, and a fire suppression system.
The flat-bottom Alcantara-wrapped steering wheel has a yellow centering stripe, paddle shifters, and buttons for various vehicle functions. The Porsche-branded digital display features integrated shift lights, and the digital odometer indicates 17k kilometers (~11k miles) along with three hours of run time on the engine.
The 4.0-liter flat-six was factory rated at 500 horsepower and 339 lb-ft of torque and was rebuilt in 2023 by Porsche Motorsport North America of Carson, California. A receipt from the work totaling over $38k is provided in the gallery. The fluids and filters were changed in preparation for the sale.
Power is sent to the rear wheels through a seven-speed PDK dual-clutch transaxle with Porsche Torque Vectoring Plus. The seller tells us that a replacement gearbox was installed at the time of the chassis replacement.
