Thanks for the info fellas, that's kinda what I figured. If memory serves, somebody was trying to fit up some Vikky rotors. I think in '05(?) they were 5x4.5, 12" diameter and very very nearly the same hat depth- two thousandths different maybe? My thought there being an off the shelf rig, and if needed the caliper could be relieved ever so slightly for the 11.6 to 12". Maybe with the PBR's, a fella wouldn't even have to...?
