0 offset. Spare fit just barely without brake light extension. I ended up buying the extension from RPG just to have it look a little better aesthetically.
I just got my Wildtrak back from RPG yesterday. Had collars put on front and back. I went with 2.25” up front and 1.5” in rear. Bronco sits within a .25” of level. Ride is definitely a little firmer, but still nice.
