Race Format: Each event featured a 100-mile distance, typically lasting 45–60 minutes, with rolling starts and full-course caution periods as needed.
Driver Eligibility: Both professional and amateur drivers competed, though the TA class was dominated by full-time professionals like Gentilozzi and Scott Pruett.
Team Structure: Teams operated with 5–10 crew members, including engineers, mechanics, and pit strategists, supporting one or two-car entries.
