Now there are some rotors out there that are massive and do require complete stystem upgrades like Bear and Brembro performance packages, but those rotors are somewhere in the neighborhood of 17-18 inches in diameter. My aftermarket ones are 1.25inches larger than the stock ones.

I'm going to let you think about that some more for a bit.
