Excessive wear on the inside is probably 1 of 3 things Brendan:
1. Excessive negative camber. i.e. The bottom of the wheel sits out further than the top of the wheel. (the "phat cause they are fully on an angle bro " of which you speak ) or,
2. Excessive toe out. i.e. the front of the wheels are further away from the centreline of the car than the rear of the wheels. They "point out" like each wheel is turning in a different direction. However, the amount of toe out required to do this would make the car very twitchy.
3. The tyres were worn on the outside and swapped over on the rims to hide the problem.
I'd go with 3 or 1.
