Ok I dont know too much about this, but what I do know is that Hot Version is preparing a video at Sendai Highlands circuit to Battle the New GTR's. They have 3 Garages that I know of with different GTR's:
MCR
Sunline
Mine's
Heres is a couple pics I found about it, if anyone has more info please share it...It sounds very intersting and I cant wait for the Video....
