Qualifying

Tom Blomqvist (pictured in 2022) helped take the No. 60 Meyer Shank Racing Acura's second pole position of 2023.

Saturday’s afternoon qualifying was broken into three sessions, with one session for the GTP, LMP3, and GTD Pro and GTD classes, which lasted for 20 minutes for the GTP session, and 15 minutes for the LMP3, and GTD Pro/GTD sessions.^[8] The rules dictated that all teams nominated a driver to qualify their cars, with the Pro-Am LMP3 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 GTPs ahead of the LMP3, GTD Pro, and GTD cars.^[19]

The first was cars in the GTD Pro and GTD classes. Jack Hawksworth qualified on pole in GTD Pro driving the No. 14 Vasser Sullivan Racing entry. Roman De Angelis qualified on pole in GTD driving the No. 27 Heart of Racing Team, besting Frankie Montecalvo in the No. 12 Vasser Sullivan Racing entry.^[20]

The second session of qualifying was for cars in the LMP3 class. Gar Robinson qualified on pole for the class driving the No. 74 car for Riley Motorsports, besting Orey Fidani in the No. 13 AWA entry.^[21]

The final session of qualifying was for the GTP class. Tom Blomqvist qualified on pole driving the No. 60 car for Meyer Shank Racing, beating Ricky Taylor in the No. 10 Wayne Taylor Racing with Andretti Autosport entry by less than one tenth of a second.^[22]
