GT3 is a customer racing class developed by manufacturers to a shared FIA technical regulation, designed so that teams can run competitive machinery without a full factory budget. Cars are built by marques such as Porsche, Ferrari, Lamborghini, BMW, and Mercedes-AMG, then sold to privateer teams for use in championships worldwide. Balance of Performance (BoP) adjustments equalise lap times across different models, making GT3 the most widely-competed GT category on the planet.
