Polesitter Ross Gunn kept the lead in the No. 23 Heart of Racing Aston Martin Vantage at the start, and the run to the first pit stops was uneventful for the PRO contenders.
Antonio Garcia was the first to pit, bringing the No. 3 Corvette Racing Chevrolet Corvette in 47 minutes into the race, with Jordan Taylor going into the car.
Pitting early and thus taking less fuel paid off later, as the Corvette had track position after the round of pit stops was completed.
But the strategy that got Corvette to the front was negated when Ellis, while trying to pass Martin for GTD position, got pushed off track in The Snake and took out a trackside WeatherTech sign. He carried the sign with him, but there was enough debris on track that a full-course caution was called.

That meant that almost everyone pitted when the pits opened, except for a handful of GTD teams that needed the benefit of track position.

Corvette needed a long fill, and lost the track position it had gained, with Taylor falling behind Mathieu Jaminet in the No. 9 Pfaff Motorsports Porsche 911 GT3R, John Edwards in the No. 25 BMW M Team RLL M4 GT3 and Ben Barnicoat in the No. 14 Vasser Sullivan Lexus RC F.

With the green flag waving with 1h8m left in the race, no one could make the end on fuel, although some, including Heart of Racing which had to serve a drive-through penalty for the No. 23 for working outside the pit box in their last stop, gambled on a late-race yellow to make that happen. Instead, most pitted as soon as the window to make it to the end on fuel opened, including Pfaff who took rear tires and a few seconds worth of fuel.

Jaminet, though, had a host of GTD cars that did not pit in front of him, and Alex Riberas in the No. 23 Aston Martin.
But Riberas was trying to save fuel, so both Jaminet and Taylor got by before he finally ducked into the pits.

Jaminet and Matt Campbell took their fifth victory of the season, with Taylor and Garcia in second in PRO and overall for Corvette. Garcia and Taylor took sole position of second in the GTD PRO championship from Barnicoat, who finished third in PRO with Jack Hawksworth, but ninth overall.

“It was super tight,” explained Jaminet. “Guys went on different strategies without stopping. And we only took two rear tires, which is not very common, and the car was super hard to drive. I had to push that out. We were pretty tight on fuel at the end. So we had quite some big savings that we had to do last two laps. And we knew the Corvette is going to catch back. So it, was pretty tight and then on the cool-down laps, we run out of fuel, so it was a good calculation from the boys. We maximized everything, and it’s one more win in the bag.”

Jaminet and Campbell only need to take the green flag at Petit Le Mans to claim the inaugural GTD PRO championship.

“It’s hard to beat a season like the one we’ve had,” said Campbell. “It’s fair to say we’ve been pretty dominant.
We’ve only been off the podium once the whole year, so I think it just shows the level that the whole team of Pfaff motorsports is at. Mathieu has done a fantastic job all year and as a group we’ve been working really well together.
So I think as a package, we’ve for sure being the strongest down pit lane overall in all areas, which is very, very cool.”
