With just three hours remaining, its setting up to be a two-car duel for the overall victory in the Rolex 24 at Daytona.
After the 20th full-course caution, it was Filipe Albuquerque who led the field back to the green flag, but ominous smoke started to leak out from the back of the Action Express Corvette DP. He gave up the top spot and went to the garage with a broken drive shaft, promptly returning to the race, but now six laps adrift of the Taylor machine.
Their misfortunes granted Wayne Taylor Racing the top spot. Max Angelelli held off Johannes van Overbeek for the remainder of the hour before another round of pit stops, where he was replaced with Ricky Taylor.
In the GTLM ranks, the No. 4 Corvette was slammed with a minute-long penalty for running a red light on pit road. The sister No. 3 currently holds onto the class lead.
In PC, the No. 85 has used up a lot of its once 20-lap cushion, but is still five laps clear of their closest competition.
The GTD battle is as tight as its ever been with Leh Keen in the No. 22 Alex Job Racing Porsche heading the group.
