Overview
- Jack Aitken’s Action Express Cadillac #31 set a 1:33.939 in qualifying but was sent to the back of the GTP field, handing pole to Meyer Shank’s Acura #93.
- The top six GTP cars were covered by less than half a second, with Porsche next-best while both WRT-run BMWs struggled after a hybrid-system issue and a spin left them ninth and tenth.
- Jeremy Clarke secured LMP2 pole for Inter Europol’s Oreca #43 by 0.008 seconds over P. J. Hyett in AO Racing’s #99 after a tense session-ending flurry.
- GT grids shifted as well: Corvette’s #3 took GTD Pro pole and Heart of Racing’s Aston Martin #27 topped GTD, while the Paul Miller BMW #1 was penalized to the back of GTD Pro, promoting RLL’s McLaren #59 to the front row.
- Night practice ended with a major pit-lane fire for 13 Autosport’s Corvette #13, and separate incidents involved contact for United’s LMP2 #22 with Van der Steur’s Aston Martin and a lost wheel for the GTD polesitter.
