†The round at Long Beach was capped to 40 cars, with only 10 GT-Cup cars guaranteed a place. Any GT-Cup entries that were not able to contest the Long Beach round were eligible for double points at Barber Motorsports Park.^[5]

News

The second race at Belle Isle on May 31 was cancelled on safety grounds due to inclement weather, which caused reduced track visibility. An additional race was held at Road America to replace the round at Detroit.^[6]
