Next year, FIA GT3-spec cars will be able to enter the Tudor United SportsCar Championship, the highest tier of the IMSA series. However, reports suggest that they are also planning a new standalone GT3 sprint race championship, which could start as early as 2016.
Details released suggest that the championship would feature six to eight events, each with two races of less than 1 hour each. These would likely run as support races on the Tudor USCC race weekends. It is still unclear whether we can expect to see 1 or 2 driver teams.
A GT3 championship could be attractive for many manufacturers, considering the growing success of the Pirelli World Challenge. Under the IMSA name, it would easily get recognised, and race wins would mean more than a class win in the current equivalent GT Daytona class.
