The No. 51 Panoz Avezzano GT4 of Preston Calvert was third 0.070 seconds back, while the No. 88 BMW M4 GT4 of Gregory Liefooghe and Henry Schmitt was just a further 0.002 seconds back in fourth.
Three of the top four spots all to Am class competitors with the No. 14 GMG Racing Audi R8 LMS GT4 of Alex Welch and James Sofronas in fifth overall and second in Pro-Am.
Harry Gottsacker was sixth overall and second in the Pro-Am class in the No. 69 SIN R1 for Racers Edge Motorsports, while Lawson Aschenbach posted the seventh fastest time in the No. 1 Camaro.
