The GT Association (GTA), sanctioning body of the Autobacs Super GT Series, has released the Balance of Performance (BoP) tables for the upcoming first round of the 2017 season at Okayama International Circuit.
The Balance of Performance for the GT300 class is tuned by the GT Association and the Stéphane Ratel Organisation (SRO) to ensure a level playing field between the JAF-GT category vehicles and FIA GT3 category vehicles, as well as each vehicle in the two categories.
