Yep, the suspensions need to go. The boss 302 with custom suspensions is faster around MMP over the new 5.0 school cars with the upgraded suspensions. If I remember correctly they have to use 285s all around in the new GT but not on the Boss.
I don't like the front of the GT, it's too Ford Fusion-ish to start with but it's not muscle car look. 2015 was better, curses the laws of aerodynamics. It's too slick. I don't like the crease in the hood either, it even annoys me from the driver seat. They did fix it with the GT350. I'd have liked the top of the nose clip to extend a hair more and they did that on the 350. I don't like the lower grill closing inward on the 5.0 and the 350 has the fangs going outward removing that lower grill shape. The hood shape is miles better and that side fender scoop is perfect. Anyway man, it's just me ... personal preferences.

Here's both in the same color-ish:
.... oh and ... you need that exhaust cup out ... no really you do.
