With a big push from Mazda, but open to competitors in all makes, the inaugural GT3 Challenge presented by MPI race took place during the SCCA’s American Road Race of Champions (ARRC) at Road Atlanta. The race attracted a field that included some of the top GT3 competitors east of the Mississippi to take advantage of increased competition, incentivized by increased contingency, the opportunity to win numerous prizes, and subsidized entry fees.
Multiple SCCA GT3 National Champions competed in the GT3 Challenge presented by MPI. When the dust settled, it was Jeff Dernehl in his third-generation RX-7 taking both the ARRC race on Saturday and the GT3 Challenge race on Sunday, which brought out two more competitors than Saturday’s event. Stacy Wilson finished second in his second-generation RX-7 and Richard Grupp was third in an RX-3. Courtesy of MPI, whose interest in the GT3 Challenge primarily stems from wanting to give back to the racing community, each of the podium winners for Sunday’s race were awarded a special MPI trophy.
