Four brands filled the top four, with the #268 Team BRM Audi third after a strong effort by Alex Peroni, while Matt Campbell moved the #911 Absolute Porsche to fourth in the dying seconds.
The session wasn't without incident, though, after Maxime Martin limped the #888 Team GMR Mercedes-AMG back to the pits early with a puncture. The #888 ended up 26th.
Kelvin van der Linde put the #32 BMW on the pace straight away, turning in consecutive fastest laps of 2:10.9234s, 2:07.4630s and 2:05.3918s.
The sister #46 BMW of Farfus lowered the number to a 2:05.0714s, as Martin limped the #888 Mercedes-AMG back to pit lane with the puncture.
Tony D’Alberto went into the 2:04s in the #93 Lamborghini with a 2:04.7392s, before Lee Holdsworth went even quicker in the #9 Audi with a 2:04.5334s.
As the session wore on, the pace continued to rise. Kai Allen was a surprise pace-setter in the #100 Mercedes-AMG with a 2:04.3854s, before Cam Waters turned up the wick.
Aboard the #222 Mercedes-AMG, Waters clocked a 2:04.1558s to put nearly 0.3s on the field, with Alex Peroni slotting the #268 Audi into second with a 2:04.1610s.
Into the final 10 minutes, the #32 returned to the top at the hands of Weerts, who clocked the first 2:03s of the day, a 2:03.8685s.
