Practice 1 is in the books for Pirelli GT4 America at Sonoma Raceway, and the 2026 season is off to a fast and tightly contested start. NOLASPORT’s No. 47 Porsche 718 Cayman GT4 RS Clubsport of Matt Travis and Matheus Leist set the early benchmark with a 1:42.514, narrowly ahead of ACI Motorsports’ No. 25 entry, while Blackdog Racing’s No. 33 McLaren Artura GT4 completed the overall top three. RS1 led the way in Silver with the No. 028 Porsche, and Random Vandals Racing paced the Am class with the No. 188 BMW M4 GT4 (G82) EVO as the field got its first full read on the Sonoma weekend in dry conditions.
