IMSA: Virtual rain-out ruins Petit Le Mans FP4

For the first and maybe last time, a GT Daytona class car topped a practice session for the TUDOR Championship.

In grim conditions on a rain-soaked track, the Muehlner Motorsports Porsche 911 GT America (ABOVE) was the sole car to complete a timed lap of the 2.54-mile course in fourth practice for tomorrow's Petit Le Mans enduro, with Mark Kvamme working down to a 2min08.335sec on his seventh of seven laps. That gave him a respectable average speed (for the conditions) of 71.251mph.

The Park Place Motorsport GTD Porsche of Lindsey/Siedler/Estre/Skeen completed an out lap, as did Renger van der Zande in the Starworks Motorsport PC car, but neither set a time.

With heavy rain forecast also for qualifying which was due to start at 4.20 p.m. local time, recently returned chief steward Beaux Barfield is considering bringing forward qualifying or setting the grid on points.

The race, the concluding round of United SportsCar's inaugural TUDOR Championship, will start at 11.15 a.m. tomorrow.
