I would vote for "No Wheel Spacers" as well. However, I do run some 1.5" spacers on my TJ when I went to 37's. I have properly back spaced wheels on it, but it still rubbed and shortened my turn radius too much. Luckily I didn't have that issue when putting 37's on my JK. Proper back spaced wheels left no rubbing on the JK. If you do have to run them, make sure you loctite the spacers on. I have ran those spacers for a couple years without issue. Having said that, I would avoid spacers if at all possible.
