The preliminary calendar was released on July 1, 2023, featuring 14 races across seven rounds.[1] On July 17, the VIR round was moved from June 15–16 to July 19–21, to avoid a clash with the 24 Hours of Le Mans.[2] An additional change was announced on September 7, with Barber Motorsports Park returning to the schedule for the first time since 2016 and Sebring replaced NOLA Motorsports Park.[3]
Championship points are awarded for the first ten positions in each race. Entries are required to complete 75% of the winning car's race distance in order to be classified and earn points.
