Giovinazzi’s #51 499P Le Mans Hypercar dipped under the benchmark time set in opening practice by Sebastien Buemi’s #8 Toyota GR010 LMH, posting a best lap of 2m01.871s.
That proved 1.278s faster than Molina in the second Ferrari, which spent much of the first half of the session in the garage before its 2m03.149s lap.
Earl Bamber put the #2 Chip Ganassi Racing-run Cadillac V-Series.R LMDh third with a 2m003.338s early in the 90-minute session before the first of two red flags triggered as two Hypercars hit trouble.
The sister Ganassi #3 Cadillac which is contesting the full IMSA SportsCar Championship season and making a WEC cameo at Spa stopped on track in Renger van der Zande’s hands at the same time as Dane Cameron’s #5 Penske-run Porsche 963 LMDh lost power.
The second works Porsche also lost track time as Andre Lotterer stopped the #6 machine with hybrid problems.
Ryo Hirakawa improved to fourth in the lead #8 Toyota shortly before the second red flag caused by an incident involving the GTE Am Ferrari 488 GTE Evos of Thomas Flohr and Diego Alessi at Raidillon.
The Japanese logged a 2m04.380s which was 2.509s off the outright pace and over a second slower than its FP1 effort.
