 Some Additional Comments by Andy Cost

I just want to clarify that positive camber is where the top of the tire leans out away from the car. Negative camber is where the tire leans towards the car.

For good handling you should always have negative camber.
For good road manners you should have positive caster.
For good tire wear you should have a tiny bit of toe-in.

My suggestions are:

-1.5 degrees camber
+1.5 degrees caster
1/8" toe-in
