I got this 1999 Mustang GT Convertible 5-speed I want to fix up. The tires are bald on the rear, so instead of just getting new tires, I want to save for some cool wheels and tires. I like the Krager Mag look (american muscle) but I have no clue what off-set to get. I want that mean hot-rod look with staggered tires. Wider in the back.

Any recommendations???

 

Anything sold by any of the Mustang specific aftermarket retailers will have correct offset/backspacing. You can also use the measurements listed on their wheels as a guide for purchasing wheels elsewhere that may be more of the "universal" fitment.
