Porsche 991 GT3 Cup

The vehicle in detail

Launched in 1986, Porsche’s 911 Cup series created a one-make championship of identically prepared cars. The format carried through each 911 generation and led to the 991 GT3 Cup in 2013 and the updated 991.2 for 2017. The 991.2 GT3 Cup introduced a more durable 4.0-liter flat-six with rigid rocker arms, centralized oil feed, improved defoaming, and a strengthened crankshaft, rated at 485 hp and 354 lbs./ft. of torque. Its six-speed paddle-shift sequential gearbox was paired with longer service intervals, resulting in engines lasting 80 to 100 hours and gearboxes for 60 hours. Upgrades included a 380 mm slotted-steel braking system, lighter aluminum-steel composite construction, revised aerodynamics, FIA rain lights, and an enlarged roof rescue hatch.

This 2017 GT3 Cup wears a Gulf Racing livery over white paint. A committed racer, Curtis Leaverton actively campaigned the motorcar in events such as the 2022 SVRA Sebring SpeedTour and the 2024 WeatherTech International Challenge at Road America, participating in multiple qualifying and feature sessions. Throughout his ownership, the car was supported by Wolf Motorsports of Elkhart Lake, Wisconsin, a respected preparation shop known for managing competitive Porsche race cars. Presenting much as it last appeared in competition, this GT3 Cup is offered with an extensive spare-parts cache consisting of bodywork, wheels, brake rotors, and additional components. Eligible for numerous competitive events and track days, it provides a compelling opportunity to acquire a Porsche factory-built race car.
