Porsche has announced details of the new GT3 Cup S, which will race in international championships run to
FIA GT3 regulations during the coming season.
The new model will make a clear definition between the 911 GT3 Cup cars and the GT3 Cup S, which is aimed solely for use in GT racing and will feature a raft of developments, including an increase of power to 440bhp.
In contrast to the GT3 Cup, the body of the Cup S is not based on the road-going GT3, but on the GT3 RS and considerably larger wheels can now be used. At the front, the rims measure 10.5 inches in width with 12 inch wheels fitted at the rear. The front section and flares are significantly different to the GT3 Cup components. An adjustable front-splitter generates more downforce at the front axle. The rear-wing is wider and positioned higher than the Cup version and provides more downforce at the rear axle.
Several suspension components for the GT3 Cup S have been taken from the more powerful GT3 RSR which races in the GT2 class in international long-distance events. The braking system of the GT3 Cup S has been developed to match the increased power compared to the GT3 Cup. At the rear the diameter of the brake discs has grown by 5mm to now measure 355mm.
Porsche will also offer a kit to upgrade the 2007 Cup models to GT3 Cup S standard.
