Do you have the off set bushing installed. That might be all the caster they can get with facotry bushings as these cars were spec for negative caster. (Why is anyones guess )

I don't like positive camber either. I would have gone for 0 to neg .5 deg.

The large difference between the caster #'s is part of the problem as well. I don't like to see more than 1/2 deg difference between the 2 sides be it camber or caster.
