The #62 Ferrari retired from the lead with engine issues in the middle of the night, moving the Corvette’s back to the front, #4 leading #3.

Colin Braun led PC in the #54, Antonio Garcia GTLM in the #3 Corvette, and Jeff Segal GTD in the #63 Ferrari. The #02 came in for a regular stop, with brake work on the right front also taking place and Kanaan remaining in the car and retaking the track in third behind the #01 and #10.
A full-course caution came out at 6:54. Both the #01 and #02 came in under caution. Hand remained in the #01. The #02 decided to take advantage of the yellow to do further brake work, but cycled back out in front of the pace car and remained on the lead lap, the #10 moving to the front.
The green came out at 6:35. With 6:16 left, the #4 led GTLM with the #93 Viper SRT (Dominic Farnbacher) in front in GTD.
Joao Barbosa leapfrogged three competitors shortly before the end of the 18th hour due to quick work by the Action Express pit crew. Jordan Taylor was running second. Corvette Racing’s pair of C7.Rs ran 1-2 in the GT Le Mans (GTLM) class for the third consecutive 6-hr segment. Oliver Gavin led in the #4. CORE autosport also remained perfect, Braun surviving a second cut tire to retain the lead. The opening segment leader in GTD was also out front at the end of the third 6 hours.
Sage Karam brought the #01 in reporting clutch slip. Ganassi was penalized for having too many crew over the wall. Meanwhile the #10 passed the #02 on track for the overall lead.
With 1 hr 35 min left in the race the #10 (Jordan Taylor) led the #02 (Scott Dixon) by 4.116 sec and the #5 Action Express Corvette DP (Sebastien Bourdais) by 21 sec. The #01 continued to experience mechanical problems. Antonio Garcia (#3 Corvette) led Dirk Werner (#25 BMW) by almost 1 min, the two holding a 5-lap gap on the #4.
Five minutes later and Dixon had closed to 1.9 sec behind Taylor. Braun continued to lead PC in the #54 CORE autosports entry and Farnbacher GTD in the Riley Motorsports Viper. The #01 officially retired.
Taylor pitted at 1:06, Dixon retaking the lead. The #02 pitted 3 min later, Dixon staying behind the wheel. Dixon came out in front of Taylor. Mike Skeen and Cooper MacNeil began grousing about the Viper’s GTD dominance, Skeen tweeting “What’s the best way to win the #Rolex24 in GTD? Bring a GTLM car” and MacNeil offering an “Amen” in response. Tommy Milner got in on the act too: “That thing has more motor than any other car by a lot. Feel for you guys.”
The #10 pitted with 40 min left. The #02 followed one lap later. Dixon retained the lead. Braun’s PC lead stood at 54 sec. The PC-leading #54 CORE entry left the track at Turn 5 with 20 min to go. He got back on track, hit the wall, and burst into flames. Tom Kimber-Smith (#52 PR1 Motorsports) moved into the lead with the cars circulating under caution.
Jordan Taylor pitted with 11 min left and pit lane closed to make a driver change to brother Ricky, Jordan on the brink of having exceeded 4 hours behind the wheel out of the past 6, in violation of race rules. Bourdais moved into P2 in the #5 with the Taylor car dropping to third.
