Competitors raced on short ovals and road courses primarily located in California, with select events in Arizona and Washington. The series operated under NASCAR’s sanctioning, maintaining strict rules on car specifications and safety standards to ensure parity among entries.

• Points System: Drivers earned points based on finishing position, with 175 points awarded to the winner and decreasing increments down the field.

• Championship Format: The season-long title was awarded to the driver with the most cumulative points after all 12 races, factoring in consistency and finishes.
