Porsche 911 Carrera 3.0l RSR "IROC" Recreation

The idea of Roger Penske – one of the most influential (and successful) team owners in US motorsport – the International Race of Champions, also known as the IROC, was conceived as an off-season competition to bring together the world's best racing drivers. All 12 drivers were seated at the wheel of a tailor-made Porsche 911 Carrera RSR. The 15 cars specially built by Weissach for the TV racing series were painted in a variety of TV-friendly, bright colors from light yellow to acid blue. What was unique about this series was that the drivers were assigned a different vehicle from the pool of available RSRs at each race, so that the vehicles were not looked after and serviced by any driver team, but by the organizer IROC RSR's truly unique creations. The 15 vehicles, a hybrid of 2.8 and 3.0 liter RSRs, were built at the end of 1973 with RSR bumpers of the G series and the then new 3.0 liter 911/74 Flat-Six. However, the vehicles left the factory with the legendary duck rump and were only then individually modified.

The vehicle in detail

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

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

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

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