Cadillac became the first manufacturer to win twice in IMSA's new GTP era, as the Ganassi squad followed up Action Express's victory after late carnage at Sebring by just 3.8s over the second of the Porsche Penske Motorsports 963s that started on the front row in the hands of Mathieu Jaminet.
Bourdais had started sixth, losing two places at the start before moving up to third following the first round of stops. Van der Zande then rejoined seventh after a safety car caused by a crash for LMP2 driver John Farano, but the Dutchman made crucial passes to move into second and nailed the crucial pass for the win around the outside of Alexander Sims at Turn 3 following a final restart.
