I did the 2.5" up front and 1.5" spacer in back. Wheels I put on were 17x9 addicts, not sure bout the offset. 33" tire. I know that if you get 12.5" wheels theyre gonna stick out a whole lot, not sure if that's what you're looking for or not. Going from a stock wheel to a 17x9 for me, it stuck the tires out maybe half an inch to an inch from the wheel well. It looks pretty good to me, but imo the 12.5" on my rig would look stupid. All my opinion Oh, and my car actually sits higher in person than the pictures show. And I could not run a larger tire on my setup, the BFG's rub when the steering is all the way locked one direction or another.
Looks really good.
