Porsche’s Motorsport division has unveiled the new 911 GT3 R single-seater customer race car based on the 911 GT3 RS which was revealed not too long ago.
The same aluminium-steel composite from the production GT3 RS has been used as the base for the race car, while the roof, front hood and fairing, wheel arches, doors, side and tail sections as well as the rear lid and interior trim have been made from a carbon-fibre composite material (CFRP). Windows are made of polycarbonate.
The aerodynamics of the road car has been maxed out here. The wheel arch air vents on the front fairings increase downforce at the front axle. The rear wing measures 1,900 mm in width and 400 mm in depth. The tyre circumference at the front axle has grown from 650 to 680 mm.
The brake system of the 911 GT3 R also underwent further modifications and now offers increased stiffness and more precise control of the ABS (generation 5 Bosch racing ABS), Porsche said. Suspension is a more stiffer double wishbone at the front and multi-link at the rear, featuring 4-way adjustable motorsport vibration dampers.
The cockpit features air-conditioning for the first time, with a direct connection to the seat and driver’s helmet, helping the driver maintain concentration and constant performance.
In order to improve pit stop performance, the 120-litre FT3 safety fuel cell can now be refilled from the left or the right depending on the circuit layout. The doors and the side windows can be removed.
The racing bucket seats are now bolted at six points. In combination with the adjustable pedal box, the driver’s centre of gravity is optimized and offers increased safety in the event of an impact. In addition, the driver is protected, thanks to a side impact element positioned in the driver’s door, which consists of a carbon-fibre Kevlar aluminium construction with energy-absorbing plastic foam, Porsche said.
Other features include Cosworth color display, Cosworth logger CLU, Porsche Motorsport traction control PMTC, LED headlamps, LED taillamps and 18-inch BBS alloy wheels made as per Porsche specification.
