I was going to do it with my 14" baer rotors but still not sure about it. My bro works a mechanical engineer and was going to see if he could work up a bracket for me to fit the 14" rotors and clear the drop spindles with grinding them.
Also I was just going to do the fronts.
The front calipers will never work with 100% contact on a 14" rotor. That was the design flaw of the first series of these brackets. You cannot get the caliper close enough to the rotor hat to get 100% contact no matter how much you manipulate the bracket, therefore 15" is ideal and optimal for this setup.
You will also have to grind the spindle if running a McGaughy's drop spindle. The casting of the model number on the spindle doesn't allow the bracket to sit flush, so you really have no choice but to grind it. I also had to grind my wife's Mcgaughy's spindles when we installed her Wilwood kit, i think that's just the nature of those spindles and their castings.
No one has made a bracket for NNBS vehicles to date. I think there were a few people interested, but I don't think the demand was there, so no one made them. I'm sure if someone wanted to donate their stock spindles or dropped spindles, the creator of these brackets would do it, but no one has done it yet.
