Introduced in 1973, the RSR was a factory-built racing car based on the 911 chassis. The Porsche 911 Carrera RSR 2.8 was the first 911 to ever wear the RSR badge. Homologated for racing by the iconic 1973 Porsche 911 Carrera RS, the RSR’s racing career got off to the perfect start thanks to Brumos Racing’s overall triumph in the 1973 24 Hours of Daytona, while a factory car won the latest ever Targa Florio road race. For the privateer in the mid-1970s who wanted to go sports car racing this was the chosen weapon.
