Porsche 911 Carrera 3.0l RSR "IROC" Recreation

very good condition, ready to use!

The brainchild of Roger Penske – one of US motorsport's most influential (and successful) team owners – the International Race of Champions, also known as IROC, was conceived as an off-season competition to bring together the world's best racers. All 12 drivers were seated at the wheel of a customized Porsche 911 Carrera RSR. Specially built by Weissach for the television racing series, the 15 cars were painted in a variety of television-friendly bright colors from bright yellow to acid blue. A unique feature of this series was that the drivers were assigned a different vehicle from the pool of available RSR for each race, meaning that the vehicles were not looked after and maintained by a driver team but by the organizer. As already mentioned, the IROC RSR's truly unique creations. The 15 cars, a hybrid of 2.8- and 3.0-liter RSR, were built in late 1973 with G-Series RSR bumpers and the then-new 3.0-liter 911/74 flat-six. However, the vehicles left the factory with the legendary duck tail and were only then individually modified.

The vehicle in detail

After the end of the first IROC series, Penske sold the 15 cars to private racers and various teams in 1974.

This RSR was built more than 15 years ago by a well-known specialist in the Zollernalb district on the basis of a rust-free German 2.7l for the current owner.

In the first few years after the conversion, the 3.0l RSR was used more frequently and took part in events.

In recent years, however, driving has been “too short”, but annual visits to our house, for maintenance, to the TÜV or for the conversion to 16-inch wheels were still taken care of, so that the 11er is always technically ready for use.
