IMSA Renews Long-Term Partnership With SRO For GT4 Homologation

DAYTONA BEACH, Fla.  – It’s one of the most popular technical specifications of sports cars to compete in an IMSA-sanctioned class, and it’ll keep competing in IMSA for the foreseeable future. Currently, GT4 cars are used in the IMSA Michelin Pilot Challenge Grand Sport (GS) class. “The decision to incorporate GT4 into the Michelin Pilot Challenge GS class prior to the 2017 season continues to be a sound decision,” said IMSA President John Doonan. Eight different GT4 manufacturers, 37 different teams and 86 different drivers have competed in the GS class in at least one IMSA Michelin Pilot Challenge race. The GS class has averaged more than 28 cars per race through the first four races of the season.
