Well I havn't been in here for awhile Bob, as for the bracket question, both rotors would be the same diameter as the prelude rotors and the rotors on my wagon (the accord wagons came with a larger diameter rotor to accommodate the larger weight of the vehicle) are both 11.9". My question is pertaining to offset of where the rotor actually sits from the spindle. Being as how I am wanting to swap from a rotor behind hub to a rotor over hub i am thinking that maybe the new hub/rotor assembly will stick out slightly further making the new bracket necessary. Looks like i will have to buy some junkyard brackets and test fit both set-ups.
