The 911 GT3, an especially sporty version of the 911, was added to the model range in May 1999. The visual differences between the GT3 and the Carrera included a new front apron, subtle side skirts, a fixed rear wing, red brake callipers and 18-inch Sport Design alloy wheels. The chassis was also 30 millimetres lower than on the Carrera and had a stiffer setup.
The 911 GT3 delivered 360 hp (265 kW) and accelerated from 0 to 100 km/h (62 mph) in 4.8 seconds. The water-cooled 3.6-litre engine was characterised by compact dimensions, vibration-free operation, high power reserves, a rounded torque curve and performance. With its reinforced 4-piston monobloc fixed callipers and its enlarged brake discs with a diameter of 330 millimetres, the braking performance of the GT3 surpassed that of even the 911 Turbo.
Following in the tradition of its Carrera RS predecessor, the 911 GT3 was also offered in two different versions. The basic version featured leather bucket seats, front and side airbags, power windows and central locking. Automatic air conditioning and a cassette radio were available on request at no extra cost. For the same price, however, the 911 GT3 could also be supplied with a Clubsport package for use in motor sports. This package included a roll cage bolted to the body, bucket seats with highly flame-retardant covering fabric, red three-point seat belts and a battery main switch.
The new 911 GT3 made its debut at the Geneva Motor Show in 1999 and became the homologation basis for use in motor sports.
