Safety is non-negotiable
Cars and driver equipment must satisfy the current BCCR. Certification dates, installation details, and event-specific requirements matter.

Open weekend resources →VPI starts the calculation
VPI establishes the platform value. Documented modifications affect the as-raced total, and cars above the standard allowance receive penalty laps under the BCCR.
Team requirements scale with race length
The current BCCR requires at least two drivers for races of 8 hours or less, three for 9 to 16 hours, and four for races of 17 hours or longer.
