The newly-developed racing brake system improves the endurance qualities of the 911 GT3 Cup 991. The internally vented and slotted steel brake discs with a 38-centimetre diameter are operated by aluminium six-piston monobloc racing callipers in the front, and four-piston units at the rear.
Two independent brake circuits for front and rear axle; adjustable via brake balance system.
Aluminium six-piston racing callipers in monobloc design; multi-piece steel brake discs, inner-vented and slotted, 380 mm diameter; racing brake pads, optimised ventilation ducting.
Aluminium four-piston racing callipers in monobloc design; multi-piece steel brake discs, inner-vented and slotted, 380 mm diameter; racing brake pads, optimised ventilation ducting.
In the race department at Weissach, the suspension underwent modifications to ensure higher precision and more stability at high speeds. Compared to its predecessor, the wheelbase grew by 100 millimetres, improving handling at the limit. PorscheMotorsport redesigned the single-piece 18 inch race rims with central locking. The width of the Michelin racing slicks at the front axle grew by two centimetres to now measure 27 cm, and at the rear axle by one cm to 31 cm.
McPherson suspension strut, adjustable in height, camber and track; forged strut with optimised stiffness, two-shear connection, heavy duty spherical bearings; wheel hub with centre lock; racing shock absorbers; forged supporting mounts; adjustable double-blade type anti-roll bar; power steering with electro-hydraulic pressure feed.
Multilink suspension, adjustable in height, camber and track; forged strut with optimised stiffness, two-shear connection, heavy duty spherical bearings; wheel hub with centre lock; non-adjustable racing shock absorbers; forged supporting mounts; adjustable double-blade type anti-roll bar.
Engineers gave the further improvement of driver safety high priority again in the development of the new Cup vehicle. Drivers are protected by a redesigned safety cage and race seat, specially moulded around the head and shoulders and individually adjustable with the help of a padding system. A rescue hatch in the roof provides easy access for primary medical attention and for the extrication of the driver. As with the road-legal car, the body of the new 911 GT3 Cup combines highest rigidity with low weight thanks to its smart aluminium-steel composite construction. The latest 911 GT3 Cup weighs in at just 1,175 kilograms.
Porsche builds the new 911 GT3 Cup on the same production line at the Porsche factory in Stuttgart-Zuffenhausen as the road-going 911. At the Motorsport Centre in Weissach, the race car gets a basic set-up for the circuits and is taken through its paces by a professional race driver. The Porsche 911 GT3 Cup is the world’s most-produced and best-selling race car, with well over 2,600 units manufactured since 1998.
