Caster & Camber VS Height

RRR hit the nail on the head. These new computer machines give you a print out with green and red and all the cutsie numbers that to you and I don't mean squat. Also said above it's the shops way of showing the customer "See all adjustments are in the green so all is good".
I also agree to keep the caster as close as possible as that 1/2* difference will cause the car to pull. As RRR said we did use caster to compensate for road crown back when they would crown the road to the right for water run off. Some states still do it and can be clearly seen with a trained eye.
So all that aside, You are setting the car up to handle,thus going negative on the camber and getting as much positive caster as the cams allow. I have RRR beat by a few years. I started using a John Beam(NOT Jim Beam )Vis-u-liner back in 1972 when these cars were the latest thing on the market. I still use turn tables,trammel bar, and bubble gauges to do alignments today. You have to be at least 60 years old to know what a trammel bar is (or close to it ! ). Keep checking around you may find a grey beard that will know what you want and how to do it ! Good luck
