Custom BoP
Last updated:
Custom BoP (Balance of Performance) is designed to ensure fair competition across the diverse range of GT3 cars by equalizing performance without eliminating each car's unique characteristics. BoP adjustments are implemented by the developers to level the playing field on a per-track basis, using tools like ballast and air restrictors. Ballast adds weight to a car, affecting acceleration, braking, and cornering, while an air restrictor limits engine airflow, reducing horsepower and top speed.
Note: Minimum ballast value -40 Kg of weight removed, maximum is 40 Kg of weight added.
