You don't have to change the spindles, if you want to go to a wider wheel, like 7" to 8", or if you want to go from 15" wheels to 16" wheels as long as the bolt pattern is the same, but if you have a different bolt pattern, say 5" instead of 4 3/4" then you would have to change the rotors or have them re-drilled.
