GT Le Mans saw BMW Team RLL’s Alexander Sims top the chart with a lap of 77.818 seconds (117.505 mph), just a little more than three-tenths of a second slower than O’Ward. Sims was an eighth of a second faster than teammate Nicky Catsburg in the no-longer troublesome No. 24.
In GT Daytona, 3GT Racing’s Jack Hawksworth was quickest with a lap of 80.031 seconds (114.256 mph), fastest of the weekend for GTD. Hawksworth’s lap was two-tenths of a second faster than Connor de Phillippi in the Montaplast by Land-Motorsport Audi.
