i'm wanting the same wheel size too but can't figure out what tire size. what size did you run up front to keep from rubbing? did you have your rear axle centered after you lowered it?
I will look into those questions when I get home. It was a great setup. The '14 is gone now too. Was almost killed last weekend, the car did its job. No bumps, bruises, nor soreness. So happy with Ford I'm picking up my 8th Mustang tomorrow. Picking up a '15 TY 5.0.
