The 997 GT3 RS was released in North America in spring 2007.
The 997 GT3 RS is 44 lb lighter than the standard 997 GT3, weighing in at 3,020 lb. This weight-saving was achieved by the use of an adjustable carbon plastic wing, a steel engine cover, and a lightweight plastic windscreen. The weight savings gives the 997 GT3 RS corresponding engine power to curb weight ratio of 300 bhp per tonne.
The body of the 997 GT3 RS is 2.5 in wider at the rear than the 997 GT3. The muscular-looking rear end conceals a wider track that not only improves directional stability but also increases the potential cornering grip. However, drag is increased and top speed reduced due to the larger rear wing. In addition to the new technology, the paint scheme and body panels are all designed specifically for this car. The limited edition RS Green and RS Orange color was formulated specially for this car.
The US version of the 997 GT3 RS has a standard rear window and the smaller 911 fuel tank to comply with rules of SCCA, Can-Am, and IMSA. For Grand-Am races, the central locking wheel nut is replaced with the standard five-lug pattern required under Grand-Am rules.
Production of the first generation 997 GT3 RS (997.1 GT3 RS) ended in 2009. An estimated 1,168 vehicles were delivered worldwide, with a total of 410 units sold in the United States and 42 units in Canada.
