You are going to have to redrill for 5" on an 11" (factory 11"s are all 4 3/4) They do have differant bearings to watch out for.

Why not just put the bigger 5x5 rotor in a lathe and turn off some OD?

That would be against most tracks rules and for sure against IMCA rules if he runs at those tracks.

Used to do this at Harris Racing all the time, either redrill the 11" rotors to 5x5 or turn the 5x5 12" rotors down 1" and put them on the 11" spindles providing the bearings are the same.
