Daytona Prototypes: Introduced in 2003, these cars featured closed-cockpit designs and were limited to 600 horsepower to ensure parity across different chassis and engine combinations.
Balance of Performance (BoP): Grand-Am used weight adjustments and air restrictors to equalize performance between different models in the GT class.
Driver Ratings: Drivers were classified as Platinum, Gold, Silver, or Bronze, influencing team lineups and ensuring amateur participation.
Race Formats: Events ranged from 2.5-hour sprints to the 24-hour endurance classic at Daytona, testing both speed and reliability.
Points System: Teams earned points based on finishing position, with bonus points awarded for laps led and winning the race.
Safety Protocols: The series enforced strict crash standards, including roll cages and fuel cell integrity, to protect drivers during high-speed impacts.
