Suzuka Circuit is a custom track recreated by lgmb. It was made with references to the track in Gran Turismo 6 and Google Maps. This track actually exists in Japan, and there are four variations of the track: "original", "east course", and a "fun edition" for both the original and east course variations. Also, there is a road that leads to hidden areas, which will contain a password to obtain the character textures "Biker Peach" and "Ike Kong".
This track only runs on slots 3.1 and 7.1 because of the object pylon01.
