The special RS model came without most of these luxuries to focus more on track-orientated driving (although the car is still road-legal). The RS trim also included a full roll cage and carbon fibre seats along with a large fixed rear wing to add to that race-car-for-the-road feel. The RS version was introduced in Europe in October 2006; the North American release was in March 2007. A racing version of the GT3 RS debuted in 2007, and it was called the 997 GT3 RSR.
