Rubbing? Oh yeah! The spacers were needed for clearance at the upper control arm. Could've got by with 1/2" but I wanted the front out a little bit. Along with that and the front only lift/level, I was shooting for a stance similar to the baja trucks. Without the mudflap mod, I still had only 22-23° of turn availible till I could hear rubbing. After removing the rear fender mounting bracket and pulling the inside of the mudflap to the frame rail, I get 35ish° which is almost full lock.
