In third, Harry Tincknell was just over half a tenth away from Conway, almost a tenth and a halved behind van der Zande, in the #55 Multimatic Mazda RT24-P. That left the Wayne Taylor Racing Acura ARX-05, driven by Ricky Taylor, to pick up the pieces in fourth place.
In LMP2, Nico Lapierre set a time of 01:36.153 and led the way in the #52 PR1/Mathiasen Motorsports ORECA 07-Gibson, with Ben Hanley in #81 DragonSpeed ORECA 07-Gibson more than two tenths off the Frenchman.
Job van Uitert was hot on Hanley’s heels, though, with the #29 Racing Team Nederland ORECA 07-Gibson driver just over four hundreths away.
Jeroen Bleekemolen was the only LMP3 driver faster than a GTLM car. The Riley Motorsports Ligier JS P320 driver was almost four tenths quicker than Colin Braun in the CORE autosport Ligier JS P320, topping the time sheets with a 01:42.416, Third in class was the #6 Muehlner Motorsports America Duqueine D08, driven by Kenton Koch.
