Think there is a very comprehensive pbr catalogue online with all of the info you require. I chose magna awd rotors at 297mm and same as Gsr otherwise on all measurements
And there is another gto rotor that is 304mm(I think, well its over 300mm anyway)
Also evo 4 is 294mmx24mm and the right height.
and mitsubishi 380s have a 294mm with the right height but are 30mm thick (much better if you can use it)
