Yea you can make them work however you end up going extreme pad which destroys rotors
also when pushing a heavy gtr 10/10ths they die in the arse really quick
380mm will work well and have ample cooling ( and rotors r cheap as there are many option for gtr, if you want ant to get serious 2mm spacer and step up to 400mm rotor from a later model, however good luck getting them under a 18 rim)
