***WeatherTech Racing’s Cooper MacNeil described the final hour GTLM scrap between Estre, Garcia and Tandy as “some good hard racing” but “some fair and maybe some not fair.” He added: “That is GTLM; it’s hard and scrappy racing. You hope to be on the good end of it, but today we weren’t.”

***Jack Hawksworth described his final-lap pass around Patrick Long: “The 16 Porsche took no tires, and we had a bit of a gap, but we managed to close it down there with a bit better tires and made a good move there on our last stop.”
***It marked Hawksworth and co-driver Aaron Telitz’s first podium finish since the last GT-only round at Lime Rock Park in July.
***The pair of Acura NSX GT3 Evos both failed to finish the race.
