I think while well intentioned, the old guys here have done enough pontificating about avoiding crashes and how to drive. This kid came here because he's excited about his first mustang (gift or not). He didn't come here so people could talk down to him.
I say leave the driving education to...
The Dark Horse suspension, and cooling is designed specifically for track use out of the box. The fact that you took a dedicated track car and intentionally reduced its camber to zero tells me you know nothing about suspension or handling. You wouldn't do that to Nissan Altima, let alone an 80k...
Camber won't wear like that unless its very agressive (like -2 or more) or your ripping around the track on a regular basis.
That looks like toe to me, but I can't be sure until I see the whole tire.
