With modern tires, NEVER use negative caster. A recommendation that seems to fit is this.

I start with the ride height and then set the front cam adjuster all the way out and the rear all the way in. Then bring the rear out until the camber is in spec. This is all of the caster that you can get this way.
Then set the toe.

I'm about to align Alan's Barracuda with the new tubular upper control arms. I'm not so sure the above recommendation is the best for those, but it should be good for factory parts.

Hey Jim, how are you measuring? Do you have actual alignment tools? I hate being at the mercy of an alignment shop.  Sad

Yes, I have a camber/caster tool that cost me about $40. It is accurate to 1/8 degree. I'll see if I can find a link to it.
