Mathieu Jaminet was quickest for Porsche Penske Motorsport in warmup for the Mobil 1 Twelve Hours of Sebring.
The Frenchman in the No. 6 Porsche 963 posted a best lap of 1:48.398 in the 20-minute session, which ran without any major incidents.
Jaminet outpaced the pair of Team RLL-run BMW M8 Hybrid V8s, which were second and third on the time charts, followed by the LMP2 class pace-setting No. 11 TDS Racing Oreca 07 Gibson of Mikkel Jensen.
Dan Goldburg was quickest in LMP3 in the No. 85 JDC-Miller Motorsports Duqueine D08 Nissan while the No. 47 Cetilar Racing Ferrari 296 GT3 of Antonio Fuoco paced the GT ranks.
The No. 3 Chevrolet Corvette C8.R GTD of Jordan Taylor was quickest of the GTD Pro competitors, meanwhile.
Forty-six of the 53 starters set times, including the No. 9 Pfaff Motorsports Porsche 911 GT3 R, which has been rebuilt following Klaus Bachler’s accident in qualifying.
Laurens Vanthoor, who will share the Pfaff Porsche with Bachler and Patrick Pilet, turned his first laps of the WeatherTech Championship weekend after previously focusing exclusively on his FIA World Endurance Championship program.
The same was the case for Jensen and Fuoco.
While the No. 7 Porsche, which also had a crash on Friday, did not set a time, it is ready to start the race.
The Mobil 1 Twelve Hours of Sebring takes the green flag at 10:10 a.m. ET, with live coverage on Peacock and IMSA Radio.
