First introduced in 2006, the 997 RSR was built to comply with the Automobile Club de l’Ouest, the FIA-GT and IMSA as well as VLN regulations. Based on the 997 GT3, the RSR features a 3.8-litre flat-6 engine with two 30.3 mm air restrictors as compared to the 3.6-litre engine of its predecessor with 29 mm restrictors. The increase in displacement was achieved through the enlargement of the bore to 102.7 mm with the unchanged stroke of 76.4 mm. With the mandatory air restrictors, the engine is rated at 335 kW (455 PS; 449 hp) at 8, 500 rpm and 435 N⋅m (321 lb⋅ft) of torque. The engine has a red-line of 9, 000 rpm due to the increase in capacity and the corresponding reprogramming of the electronics. The new positioning of the mid-front radiator and the use of side radiators – shared with the Carrera GT – contribute to the thermal health of the engine. The 997 RSR used the 6-speed sequential manual transmission of 996 RSR for the 2006 season. For the 2007 season, a new 6-speed sequential manual transmission was added which was shared with the RS Spyder. The bodyshell with the welded-in safety cage is ten percent stiffer than the 996 RSR. Distinctive wheel arches widen the body by 50 mm (2 in) on each side. The relocation of the supplementary oil tank, power steering components and battery to the front improve weight distribution. The front and rear lids, the front mudguards, the rear section, the doors as well as the front and rear panelling and wing are made of carbon fibre. Polycarbonate rear and side windows further aid in weight reduction. The newly-developed aerodynamic package improves aerodynamic efficiency by a total of around seven percent over the 996 RSR. In compliance with the FIA and A.C.O. regulations the new GT3 RSR features a flat underbody. The RSR featured ZF-Sachs shock absorbers which have Through-Rod-System with considerably lower chamber pressure and hence generate less friction than conventional dampers.
