For Daily Race A, which is an N400 BOP race, I would recommend using a Porsche 911 GT3 (997) '09. The Toyota FT-1 Vision Gran Turismo Gr.3 is my choice for Daily Race B because Dragon Trail - Gardens has two long straights, but other cars such as the Volkswagen Beetle Gr.3, the Audi R8 LMS '15, and the Porsche 911 RSR (991) '17 will also perform similarly. Because the track used for Daily Race C, Red Bull Ring, is tight, and understeer can cause issues, I would use the Porsche Cayman GT4 Clubsport '16.
