Just a week after the races at Miller Motorsports Park, the Pirelli World Challenge GT, GTA, GT Cup and GTS classes return to action at Sonoma.
Sonoma should hopefully see the return of the K-Pax Flying Lizard McLarens after the boost limit issues in Utah.
The GTA class includes the return of 10-Tenths' Mike Hedlund in his Ferrari.
The GTS class has several extra entries, specifically Gainsco's Hyundai Genesis for Jeff Harrison, Paul Holton's Compass 360 Audi, Kevin Marshall in a Lotus Evora GT4 and three TRG Aston GT4s for new drivers Jason Alexandridis and Peter Ludwig, and one for returning driver Derek DeBoer.
