if your suspension is old, it may sag, when it sags you haev effectively lowered your ride height. The lower you make yoru car the more negetive camber there is. That is why you need an adjustment rod to adjust the negetive camber back to -.44 degrees, unless u want non stock alignment.



Could also be your toe bushings taking a dump, when they take a dump, the toe changes whenever you hit a bump causing the tires to wear out sooner.

 

I guess i'll go crazy sometime and redo it all.
