Justin Wilson and the Michael Shank Racing team lead the Rolex 24 at Daytona going into the final six hours.
Wilson has been pulling away from the field in his most recent stint, opening out a 38-second gap over the second-placed #01 Ganassi car, currently driven by Joey Hand.
The #8 Starworks car appeared to be in control for a spell, before an off by Lucas Luhr cost it time. Allan McNish is now running third for the team and attempting to get back on the lead lap.
The second MSR car, Action Express Racing's #5 Corvette and the #02 Ganassi entry complete the current top six.
