Talked to my mechanic friend whose doing the alignment for me. He recommended me to not dial it too agressively. Instead of focusing on the final number, to focus on how much change I am dialing in. At the limit, the dynamics of the vehicle can change quite drastically if the alignment is tweaked too much. Only after being comfortable with the new setup, then should I retune it for more or less camber/toe as desired.
This is from the top of my head. I still haven't got my car back yet. Picking it up later along with final alignment numbers. What I had before.
Front -0.5 camber, ~.1 toe in
Back -1.9 camber, ~.2 toe in.
Front -1.6 camber, ~0 toe.
Back -1.9 camber, 0.08 toe in.
Apparently, -1.8~-1.9 of rear camber is the default factory spec for the rear camber. So it's actually staying with factory spec here.
