The Classes

 The IMSA-sanctioned Ultra 94 Porsche GT3 Cup Challenge Canada by Yokohama enters its seventh season in 2017 ready to produce more intense, exciting competition for semi-professional and aspiring professional drivers in the world’s most produced and iconic race car, the Porsche 911 GT3 Cup, and the Porsche Cayman GT4 Clubsport. The championship is one of 20 Porsche single-make Cup Challenge series in the world.

Racing is divided into two classes – Platinum Cup, featuring the new-for-2017 Porsche 911 GT3 Cup car, which is based on the current generation of the street car; and Gold Cup, which is comprised of the previous iteration (model years 2014-2016) of the race car. A Masters Championship also is conducted in the Platinum class. Each class is awarded with its own podium at the end of every race and individual champion at the end of every season. Points are awarded by finish in class.
