The gaps remained tight in GT Le Mans with only 0.597 of a second separating the top eight cars.
A late flier from Bryan Sellers in the No. 17 Team Falken Tire Porsche 911 RSR brought that car to the top of the charts at 1:19.060. The No. 3 Corvette C7.R was second ahead of the No. 912 Porsche 911 RSR, No. 93 Dodge Viper SRT GTS-R and the No. 911 Porsche 911 RSR.
