Balance of Performance

Balance of Performance (BoP) is a regulatory system in motorsport that adjusts various technical aspects of different vehicles to ensure they can compete fairly against each other despite their inherent design differences.

BoP works by modifying elements like vehicle weight, engine power, fuel capacity, and aerodynamics to level the playing field. For example, a naturally powerful car might receive weight ballast or air restrictors to reduce its advantage, while a less powerful car might be allowed to run lighter. This system is widely used in GT racing series where diverse manufacturers like Porsche, Ferrari, and Aston Martin compete.

Rather than forcing all cars to be identical, BoP allows different vehicle designs to race competitively while maintaining their unique characteristics. Series organizers continuously collect performance data and make adjustments throughout a season to maintain competitive balance.
