Took my car in to get an alignment. I now understand the significance of getting one after doing major suspension work like installing springs/coilovers. Pre-alignment the car would feel very twitchy, floaty, and I could break traction even on my 245 star specs easily. Scary.
Andrew with @
Racecomp Engineering said to take it easy because my toe could be off. Watching the screen while taking baseline measurements confirmed his suspicion. It was definitely out of spec.
Friend pointed me to this shop and I got aligned by a Hunter Hawkeye Elite. Not sure if that machine any good but it seemed legit. His computer didn't have the twins in it so he just picked a Avalon for the first go round, and a Scion iQ for the second. Overall I liked that he did it twice to be sure.
He did not like the design of the Cusco control arms. He had to drop the arm to make adjustments since the turnbuckle was in the subframe and a wrench wouldn't fit in there. If the adjustments were more out in the open he would have been golden. Dialing in the adjustment in the rear was difficult overall, when he adjusted camber the the toe would fall out and vice versa. I'll take his word for it because his experience trumps mine.
Overall he got it to a good setting as indicated in the printout below. He said when I sit in the car it'll be closer to the targets RCE recommends. I noticed an immediate improvement in stability and road going manners. The twitchiness/grip issues are gone. Need to take it out to find the upper limits
I'll post more when I can ring her out.

I believe it's missing thrust angle and SAI.

In summary, get the alignment!
