All cars were required to be driven by one participant and the starting order was determined by the competitor's fastest lap. IMSA then arranged the grid so that the DPi, LMP2, and GTLM cars started in front of the GTD field.

Ricky Taylor in the No. 7 Acura set a new track record to clinch his first pole position of the season with a time of 1 minute and 15.035 seconds.
