If there was a “classic all star game” in the racing world, it would have been the International Race of Champions (IROC). Champions from different branches of racing (SCCA, F1, NASCAR, USAC) participated in a series.
When we hear the abbreviation IROC , we think of the IROC-Z, not a 240Z, 350Z but a Camaro Z28. But as a Porsche RSR fanboy, I would like to raise awareness that before the Camaro IROC-Z, there was a Carrera IROC RSR.
