The Porsche 911 GT3 RS is a high-performance sports car built by Porsche since 2003. It is often confused with the Porsche 911 GT3 RS racecar of 2001 and later, which was based on the Porsche 911 GT3 R of 2000.

The RS (short for the German RennSport, literally "racing sport" in English) is mainly a carryover of the Porsche 911 GT3, albeit it is lighter thanks to a polycarbonate rear window, carbon fiber hood and rear wing. Porsche Ceramic Composite Brake (PCCB) Carbon fibre-reinforced Silicon Carbide (C/SiC) ceramic composite brakes, which are also more heat and fade resistant than the cast iron units fitted as standard, are optional.

The RS has a slightly different engine specification to the GT3. The cylinder heads of the GT3 RS have reshaped intake and exhaust ports for race homologation. Porsche claim the same 381 hp (284 kW) power output as the standard GT3 but Porsche's control dyno showed a jump to nearly 400 hp (298 kW)

The RS has progressive springs rather than linear. The dampers are uprated and are between 10 and 15 percent stiffer than the normal GT3 in bounce and rebound.

The wheel carriers are totally redesigned to maximize the improved dynamic camber control. The suspension top mounts can be turned 120 degrees to a cup car position. Both front and rear control arms are adjustable. The RS is 3 mm (0.1 in) lower than the standard car.

The RS rear wing delivers 35 kg (77 lb) of downforce at 125 mph (201 km/h). The RS has ram air ducts on the engine bay which force air into the intake with 18Mb of pressure at 187 mph (301 km/h) and this is enough to create an additional 15 bhp (11 kW; 15 PS). That extra bhp cannot be homologated since the official engine output figures are certified on a dyno.

Only 140 right hand drive GT3 RS cars were built by Porsche and 113 of those were officially imported into to the UK. The GT3 RS was not sold in Canada. The original Porsche 996 GT3 RS had a production run from 2003 to 2005. The "RS" moniker, and the characteristic lightweight blue or red wheels and "GT3 RS" side stickers link the GT3 RS to historically important Porsches such as the Carrera 2.7 RS of the early 1970s.
