I dont understand why all this trouble? Why not just have some brackets made for the factory hub/knuckle setup? This seem like it is much more involved and probably about the same price in the end. Unless I am missing something here?
Dont mean to be rude but just perplexed by this?
I would have used the factory hub/knuckle setup, made a bracket to use the new calipers with the U13 rotors and called it a day. That seems to be all you need ... to have the caliper positioned correct on the rotor. It looks like you have plenty of room to run these on the 15" wheel dia you have and with a 2 piece caliper you can move it into the right position so that it sits in the middle of the rotor.
you shave the over all diameter
well thats if you use z brakes thats just how some people do it on g20.net we have the same problem
because i use q45 twin piston i just shave the caliper mount (torque mount) with a grinder and it works and if you can find a machine shop to make an offset bracket that moves it out about 5mm then its perfect you probably can make that bracket your self but because the distance your moving it out is so minuscule youll end up moving the caliper backward alot
