We have had great luck and success with setting the front cambers to -.3 to -.4 when we do our Pedders systems. we also pump up the casters using the Pedders EP9166, and use caster to adjust for road crown.
I also like to have the toes on the tight end of specs. I assume you have not strut rub as well? So if you are getting negative camber wear only up front, with no cupping issues, then a normal align will do. But if you are planning bushings, then you will have to re-align after bushings installed anyways. What bushings are you going to do?
