The IROC Porsches

The IROC Porsches details the creation and first season of the International Race of Champions, a series divined as a means to pit the world's top international racing drivers (from IndyCar, Formula One, sports car racing, and NASCAR) against one another to determine who was top dog. In the inaugural 1973-74 season, each race driver was assigned an identically built and prepared Porsche 911 RSR. The IROC's contention was that if all cars were truly equal, then the drivers with the most talent and skill would shine as the victors, and thus the world's best. It proved a rollicking formula, with great drives from racers like George Follmer, Emerson Fittipaldi, Mark Donohue, Dennis Hulme, Richard Petty, and more. It also proved historic as the only season to feature Porsche's awesome 911 RSR - subsequent years would feature American manufacturers.
