It's all been done... They have caliper spacers, to allow for a large diameter rotor for more braking torque w/ the factory caliper(I know they do for the rear brakes, unsure of for the front, but pointless). You can't beat a bolt on setup such as the Brembo/Z32 brakes. More than just caliper/rotor size has to be taken into account. Brake bias will be effected if you up the ante, which leads to master cylinder changes as well.
