Joao Barbosa led overall and in P at the 10-hour mark of this year’s Rolex 24 at Daytona in the No. 5 Action Express Racing Corvette DP.
Other class leaders included Nick Tandy in the No. 911 Porsche North America Porsche 911 RSR (GTLM), Michael Marsal in the No. 25 8Star Motorsports ORECA FLM09 (PC) and Jeff Segal in the No. 555 Level 5 Motorsports Ferrari 458 Italia GT3 (GTD).
Most of the leaders were engaged in the latest round of pit stops as the clock ticked over the 10-hour threshold.
Unfortunately, the last couple hours have not been kind to the GTLM-pacesetting SRT Motorsports SRT Viper GTS-Rs.
The No. 91 went to the garage with a power steering pressure line in the ninth hour, and is now 10 laps behind the class leader after repairs. Meanwhile the sister No. 93 lost five laps with front end damage in the tenth hour.
The second factory GTLM Porsche also had issues; Patrick Long’s No. 912 911 RSR was issued a stop-and-hold plus 10 for too many men over the wall. A drive-through penalty was assessed for not serving the penalty in a timely manner.
Another car that fell out of the running in the last cycle was the No. 78 Starworks Motorsport DP, which ran as high as second overall with a lineup that included Brendon Hartley, E.J. Viso, Sebastian Saavedra, Alex Popow and Scott Mayer.
The Dinan-powered Riley suffered terminal mechanical failure on in the tenth hour, and caused a yellow when it stopped on track.
