K-PAX Racing took the next two spots with the No. 9 Bentley Continental GT3 of Andy Soucek and Alvaro Parente leading home the sister No. 3 car of Maxime Soulet and Rodrigo Baptista.
Turner Motorsport’s No. 96 BMW M6 GT3 was quickest in the Am class in 14th overall.
A red flag halfway through the session for an incident involving the No. 19 One11 Competition Ferrari of Christopher Cagnazzi brought proceedings to a halt for around ten minutes as track workers were forced to make repairs to the tire barrier in Turn 9.
