Everybody said it wasnt possible, but heres our 2015 Mustang GT PP customer running a set of Bronze Burst 20x10.5 square F14s with Super Deep Concave rears and deep concave fronts!
As far as I know, this is the first new Mustang in the world to run the super deep concave!
Tire widths aren't going to be maxed out since the more aggressive SDC fitment needs a slight stretch, but not a lot
We're currently working on a pair of 20x12 SDC for the rear so we'll see how that works!
