So it seems the 2.25" collar will be the preferred method when running 37s (other than Toyo MTs) with wheels with 0 offset (like stock wheels). Minor trimming required. Would most agree??
I think it just depends... I'm happy with it from a no rubbing standpoint and overall stance with the rear stock. For heavy off roaring though, I think you could really use the 3" and then decide on a rear setup.
