hey jason there is a guy in the indonesia who made a bracket that fits on the front wheel to give him dual rotors and dual calipers up front, if i remember right he simply duplicated the right side to the left side but theres no reason you couldn't do the same with different pots. can't find the link right now (too lazy) but he posted a writeup about it on this article... there is a great video detailing it on youtube.
