Will a larger than those regular rotors be possible? Like 14'' or anything? Or does it have to be proportionate to the caliper size?

this is an intresting question i never thought about, lets get some answers. i would think yes?

I think it might be a possibility, if you get a bracket to relocate your caliper further... anyone wana help me on this?

I mean the calipers would cover less rotor space--I see that as being a big issue...

I don't think you want to do that with your breaks. If you search for brakes you should find a few options. I know that bbk are about $2k to $2.5k for either front or rear. If you put big rotors you will need to upgrade your calipers and pads. I think there are some options at performancenissan.com.

Don't go cheep on your brakes!!!!
best to just leave it alone or just change out the pads

Yes, their is a big brake kit that relocates your stock calipers. They have a front kit and rear kit. This is the only one I know of that does this. The rotors are bigger at 13" in diameter but the thickness of the rotor is the same as stock.

Increasing diameter without increasing thickness is a half ***** solution.

Rotor mass and rotor temperature are directly related.......10% more mass = 10% lower temperature............a proper rotor would be 28-32mm thick.

I agree completely and that was the one thing that turned me off to considering their 4 pot BBK. Otherwise their attractive price and their wide availablity of pad choices (uses the same pad shape as the last gen 300ZX) were looking really good.
