I saw that as well. Yes, we don't know everything about the game, but I'm getting confused with the customisation. Do we upgrade the SVJ TO GT-1 or GTO spec? I thought the Civic Type R could be customised to touring car spec, but we have a Civic TCR spec racer.
We have a base Supra and the Supra Racer. Do I downgrade the Supra Racer to GT4 spec or upgrade the base Supra to GT4 spec?
I think we just upgrade the car to "racing" spec, whether it look like a GT3 or GT4 doesn't make a difference since the classes is all mash up. Aventador SVJ Racing is a weird one, maybe we are just upgrading a standard Aventador to SVJ Racing.
