Collin, please don't take any offense to this, but I've designed, prototyped, built, and come Friday should have the first waterjet-cut pieces in my hand of my true 330mm brake setup.
If your machinist can't figure out how CAD works, I don't mind helping you out, man. I mean, the 12.6" rotors + the 10.8" caliper fit under the stock Saws, right? That's the one disadvantage of my own kit - you MUST have 17"+ wheels with brakes as big as mine. As long as the nightpager kit fits under stock sawblades, should be really nice for those that do not wish to ditch the sawz just yet!
