I would use the 5" Backspace ones (0 offset), you may need 1.5" spacers for the rear to get the rims closer to the outside of the fender for looks.

My rims are 10" with 0 offset and I would like more backspace in the front but the ones you are looking at are 9" and would give you .5" more clearance than mine (when you go to disk). The 5.75 backspace would give you 1.25" more clearance than mine.

If you are going to change to disk, in most kits it moves the spindle out .75" so the 5.75" backspace rims would offset (no pun intended) the addition of disk spindles. CPP has no offset disk kits by the way, then you could have all the same size rims.
