Front End Alignment

Hey John, thanks for the response. I'm not looking for a pissing match either.
I cut my teeth on a A-111 so I'm not up to speed on mechanical methods. Lasers and computers do it for me.
I'm just fishing for info and you seem to be a good reference.
I get it as far as setting up the rear square to start with and measuring wheel base.

I just don't get how you can compete with a computer and all that trigonometry and still do as good of a job.
Yes, I'm sure your alignments get the job done and tire wear is fine if not better than someone with less knowledge and a brand new computer aligner, especially with modified ride heights.

But there is always going to be some setback and I cant understand how you can keep from setting the front toe equal to setback without a computer.
