and if they are GTR VSPEC : 324mm x 30mm (4 pot brembo caliper)
than you supposedly can use z32 pads and than i doubt you'd need to up your rotor size, i would just look for a slotted rotor with a better pad combination and make sure you have ss lines and that your brakes are properly functioning because those should be pretty bangin
and if your hesitant about ordering pads cause your not sure if itll work just order the brakes from a european website
