Here is a shot of my dual A assy as of today - all the numbers are exactly what I want in terms of roll center, camber gain, and overall adjustability. I now have to fully adjustable pivot points (top and bottom) that I can mess with ride height and roll center pretty much at will.

For the front I am starting with a 13.5" lower arm length, 10.5" nominal upper length, and what both calculated in my computer and was verified with my angle finder in the attached image is a parallel lower arm nets me an 11 deg upper angle for a static RC of ~2.5" which is what I was shooting for. The lower pivot is not a ball joint but monoball from Coleman and they make a set of spacers that come with it. I can swap those around to vary the upper A angle and therefore static RC but comes with a 1:1 change in ride height (move the pin up 1/4" and the car drops 1/4") so if I need to make a big change I can then just buy a longer or shorter upper ball joint insert.

I then went on to verify I could easily get -3.5deg neg camber on the front for radials. A few may note I underestimated the arm lengths I would need upon my original parts purchase (might notice some of the heims adjusted nearly all the way out) so I will be getting longer pieces on their way next week. All the upper needs is some longer tubes, the lower I just need a new tube for the caster but will need a new custom lower made as they make those to order. Not a big deal, just a few bucks blown in the process of figuring out where I am going with the car
