as the title says, whats the backspacing on the UltraStars? I have the Freedom Sport XJ and other than the radio and air filter, it's essentially stock. Looking to up the suspension because currently the 245/75/16r's which come out to around 30.5 inches rub on the fenders when hitting a bump at speed which is nearly everywhere in Alaska. Just don't wanna rub on the suspension if i lift it up 3-4 inches.
