From the 911 Carrera it evolved to the 911 Turbo S version and finally to the renewed GT3. Designed for high competition, the model is lighter and features an increase in power of 400 hp.
The new GT3 will be available on the European market under the title of Cup 2005 and its main destination is the Porsche Michelin Supercup 2005, although it will be available for other Gran Turismo competitions, including Daytona and Le Mans. Of course it is exclusive to us, it can also be purchased by private customers at Porsche dealers in mid-2005.
This 911 GT3 Cup 2005 features a six-speed sequential gearbox for the traditional 3.6 litre Boxer engine that finds its maximum torque at 40 kgm at 6,500 rpm. It is remarkable how similar to a street car this racing car results in some details, such as the use of 2 catalytic converters and exhaust tracks that converge into a single central exhaust.
Porsche achieved the goal of reducing the weight of the sports car, so it manufactured the doors in carbon fiber, as did the rear bumper and spoilers. In this way the GT3 obtained a significant reduction, reaching a minimum weight of 1,150 kilos.
In addition, the German house increased the aerodynamic load of this vehicle by adding two adjustable front spoilers in front of the fenders and more surface to the rear spoiler, which is now 35 mm higher and 60 mm wider. A total downforce increase 40% greater than the previous 911 GT3 model was achieved.
But it is on the brakes that lies one of the great technological advances of this Porsche 911.
For the first time Porsche incorporates its revolutionary ceramic compound (PCCB) into the brake discs of a racing car. The braking system is adjustable for the balance of the braking force at the front and rear. The ceramic discs are internally perforated for ventilation and have a diameter of 380 mm forward and 350 mm behind. They all use 6-piston jaws.
Although the anti-lock brake system (ABS) is a standard in modern cars, it does not incorporate it since most of the competition regulations in which it will participate do not allow it. Whether the braking distribution to the front and back can be controlled from the dashboard instrumentation.
The doors, spoiler and rear bumpers plus the engine cover are made of carbon fiber. The spoiler and front pagolpes are also constructed of carbon fiber. The rest of the body is made from galvanized steel sheets. The windows and rear window are plastic, while the windshield is made of glass.
Suspensions were recalibrated to achieve greater accuracy in the settings for each race and better dynamic response for the rider.
Front and rear suspensions feature double damper and spring with height adjustments (ground clearance), camber (skipping) and trot dimension adjustment. On the front the McPherson suspensions are complemented by adjustable anti-roll shock absorbers and anti-roll stabilizer bars, while on the rear beam the multilink suspensions have a rigid suspended structure and adjustable anti-roll stabilizer bars.
Rear suspension: bridge with coil springs and adjustable shock absorbers
Front wheels: single nut 9J x 18”
