Practice
There were two practice sessions preceding the start of the race on Saturday, both on Friday. The first session lasted 90 minutes on Friday morning while the second session lasted for 120 minutes on Friday afternoon.[14]
Qualifying
Friday’s afternoon qualifying was broken into two sessions, with one session for the DPi and GTD classes, which lasted for 15 minutes each, and a ten minute interval between the sessions.[14] The rules dictated that all teams nominated a driver to qualify their cars, with the Pro-Am (GTD) class requiring a Bronze/Silver Rated Driver to qualify the car. The competitors' fastest lap times determined the starting order. IMSA then arranged the grid to put DPis ahead of the GTD cars.[15]
