First Practice

The best time across both GT classes was set in GTD, by Scott Andrews in the No. 80 Lone Star Racing Mercedes-AMG GT3. The Australian turned in a 1m45.867s to go quicker than Caldarelli's best GTD PRO time.

The No. 36 DXDT Racing Chevrolet Corvette Z06 GT3.R was second quickest in GTD, then, it was the returning No. 44 Magnus Racing Aston Martin Vantage GT3, third quickest with its humorous new "Virtual Energy" sponsorship. In fourth was the No. 12 Vasser Sullivan Lexus.

One car that didn't set a representative time was the No. 3 Corvette Racing by Pratt Miller Motorsports car. It only posted three installation laps, then underwent a gearbox change as a precaution after the team diagnosed a faulty sensor and saw unpleasant fluid temperature and pressure readings.

IMSA WeatherTech SportsCar Championship cars return to the track tomorrow for Practice 2 starting at 9:00am ET, followed by qualifying, which starts at 2:20pm ET.
