2012 Sport S as we speak we're putting in a Rough Country 2.5 shocks/springs lift. 17" black rock rims with 4.5 backs pacing and 35" Mickey Thompson Baja crawlers. So much conflicting info. I bought them just incase (1.25") spacers. I'd prefer not to use them. Also, will I have to trim anything? Tyvm!

 

With the backspacing that those wheels have (4.5 ) you shouldn't need wheel spacers. I would recommend trimming your pinch seam in the rear. Other than that you should be fine, if you notice rubbing while flexing then you may wanna trim your fenders some.

 

Just sell the spacers, cuz u won't need them at all. Just trim the pinch seam in the rear.
