Not much is known about GT Association, aside from the fact that it probably sanctions all of the races in each game, and that it may be based off the real-life GT-Association that sanctions the Autobacs Super GT Series. The organization's main logo can be seen, among other places, in the intro movie for Gran Turismo 4, on the side of the Ford GT LM Race Car Spec II, on Gran Turismo 5's "My Home" screen (the one the player clicks to go into GT Life mode), and during loading screens for Gran Turismo 6. An alternate logo can be found on the start/finish gantry on various tracks, such as Tokyo R246, where it has been since Gran Turismo 3: A-Spec.
