The IROC Porsches: The International Race of Champions, Porsche’s 911 RSR and the Men Who Raced Them by Matt Stone © Motorbooks

This is the story of the International Race of Champions Porsche Carrera 911 RSRs and the drivers who raced them. It’s a story that is long overdue, as these cars formed an important part of Porsche’s historic rise to the top of the international motorsport pyramid.

In 1973, Porsche introduced its 911 Carrera RS 2.7 road car, but it wasn’t long before these cars were being put to the test on many race tracks around the world. The fully fledged racing version of this car at that time was the 911 Carrera RSR 2.8 of which 55 units were produced for use during the 1973 season.
