Antonio Garcia led the Corvette challenge, lapping exactly a tenth off Tandy’s best time. Tommy Milner was 0.07s slower in the second C8.R, whose teammate Oliver Gavin topped the wet session, lapping almost seventh tenths faster than Vanthoor.
Connor di Phillippi was fastest of the Rahal Letterman Lanigan Racing-run BMWs, 0.065s faster than Jesse Krohn in the sister M8 GTE.
In GT Daytona, Jack Hawksworth was fastest for AIM Vasser Sullivan Lexus, ahead of the Wright Motorsports Porsche of Patrick Long and Paul Miller Racing Lamborghini of Bryan Sellers.
Hawksworth’s teammate Aaron Telitz was also fastest in class in the wet session too, but only two GTD cars set a time.
