Chassis Porsche Supercup cars adhere to a
rear-engined
rear-wheel-drive design. A
roll cage serves as a
carbon-fibre space frame chassis and is covered by a multiple-gauge
sheet metal body. They have a closed cockpit, fenders, a rear wing, and an aerodynamic splitter. Each team may purchase cars and engines from other teams. The car has a front
MacPherson strut suspension, and a rear
Multi-link suspension.
Brake discs must be made of steel and may not exceed diameter. The only aerodynamic components on the vehicles are the
front splitter,
rear wing, solid polycarbonate glass window in the windows only, and side skirts. The use of
rear diffusers,
vortex generators,
canards, wheel well vents, hood vents, and undertrays are prohibited. Porsche Supercup cars are required to have at least 1 working windshield wiper installed on the car for all tracks as a part of the road racing rules package.
