In GTD,
a forceful pass from Kenton Koch gave Triarsi Competizione its first-ever IMSA victory.
The No. 021 Ferrari of Koch and Onofrio Triarsi took the win with eight minutes to go as Koch made a late lunge at Turn 6 to barge past the No. 36 DXDT Racing Corvette of Alec Udell and take the lead.

Udell and co-driver Robert Wickens would sink to eighth in the final minutes due to the damage they suffered.

GTD-Pro Class

A late-race pit stop for the No. 77 AO Racing Porsche 911 GT3 R handed the GTD Pro class win to the No. 1 Paul Miller Racing BMW M4 GT3 EVO of Neil Verhagen and Madison Snow in a rough-and-tumble race in the two production-based classes.
Laurin Heinrich, who appeared to have been hoping for several late-race yellows, dived into the pits for energy with 14 minutes to go, handing the lead and eventual class win to Verhagen, who picked up his first series victory.

The No. 64 Multimatic Motorsports Ford Mustang GT3 of Seb Priaulx and Mike Rockenfeller was second in class, followed by the No. 81 DragonSpeed Ferrari 296 GT3 of Albert Costa and class pole-sitter Giacomo Altoe.

Antonio Garcia made a comeback drive to finish fourth in class in the No. 3 Corvette Racing by Pratt Miller Chevrolet Corvette Z06 GT3.R., which was in the Turn 1 gravel trap after contact from the No. 48 Paul Miller BMW of Dan Harper, who spun Alexander Sims to bring out the race’s fourth yellow on a restart.
Harper was handed a drive-through penalty for incident responsibility.

Sims and Garcia remain in the class championship lead but now only 30 points ahead of DragonSpeed’s Costa with three races to go.
The class saw a significant amount of contact and incidents, and subsequent penalties for a number of contenders.

The No. 4 Corvette of Nicky Catsburg stopped on track near the Turn 4 cut-out in the final ten minutes with apparent damage following contact from the No. 9 Pfaff Motorsports Lamborghini Huracan GT3 EVO2 of Andrea Caldarelli, which resulted in a drive-through penalty to the Canadian squad.

Kenton Koch made a late-race pass around Alec Udell to give Triarsi Competizione its maiden win in the GTD class, meanwhile.
Koch took his No. 021 Ferrari to a 1.168-second win over the No. 78 Forte Racing Lamborghini of Mario Farnbacher after Udell, in the car he shared with Robert Wickens, slowed on the final lap.

It marked Koch’s co-driver, Onofrio Triarsi’s first career WeatherTech Championship win.
The No. 34 Conquest Racing of Manny Franco and Daniel Serra completed the class podium in third, in the wild second half of the race.
