best disc brakes for sbp

Bill, in the interim I was able to examine a few sets of 65-72 A disc setups for sale. I immediately noted that the rotor was mounted BEHIND the hub, giving much more clearance in a 14" rim. I could do this - modding 1983-94 Ranger 2WD hubs and have it work on either 9 or 10 inch spindles. But the SOLE virtue of this setup is the rotors are 5 on 4".

I feel our setup from a budget vs. effectiveness matrix kicks the hell out of the stock setup - and fits inside the poverty rims.
