Hour 2 at Sebring 12 ran under green, with conditions gradually improving near the end of the hour as the rain let up and portions of the track began to dry.
The two Action Express Cadillacs led throughout the hour before leader Pipo Derani pitted from the lead at the two-hour mark. His No. 31 Whelen Engineering crew opted to be the first contender to change to slick tires.
That gave the lead to teammate Filipe Albuquerque in the No. 5 Mustang Sampling entry, who had a 90-second advantage over the third-place Mazda of Jonathan Bomarito at the time.
Richard Westbrook led GTLM in the No. 67 Ford GT; Kyle Masson had a one-lap advantage in LMP2; and Zach Robichon took the GTD lead in the No. 9 Pfaff Motorsports Porsche 911 GT3 R.
Trent Hindman pitted while leading in GTD at the 1h35m mark, with Justin Marks retaining the lead in the No. 86 Acura after the stop. Robichon passed him for the lead two laps later.
“The track itself was OK; the biggest problem was the spray,” Hindman said. “I had to be really careful in the event something happened in front of me, but I knew my Meyer Shank Racing Acura would be hooked up in these conditions.”
The Team Penske Acuras both struggled in the second hour, falling off the lead lap and all the way down to ninth and 11th in the DPi class. Ricky Taylor spun at the exit of Turn 17 on lap 36, stopping momentarily in mid-track before being able to continue, but losing two full laps.
Earlier, both Action Express Racing cars had pitted on lap 27 while running 1-2, Derani’s No. 31 followed by Albuquerque’s No. 5. Derani maintained the lead despite the stop, still trailed by Albuquerque, but Jordan Taylor – who pitted for fuel several times in the early laps under caution – moved up to third in the No. 10 Cadillac. Taylor held the position through his subsequent stop, where he picked up a speeding penalty while exiting the pits.
Tristan Nunez spun early in the hour after contact in the Hairpin; he was running third in the No. 77 Mazda.
