Donny, thanks for taking the time to jump in much appreciated. Yes I have been lax on info and apologise I do get + / - camber around the wrong way, but you get my drift.
Specifically.
Yes when standing still in the garage she tilts when I turn lock to lock.
Tyres are 235x45x18 on front
It is running a C5 vette spindle
front airbags are on separate air lines and it's running Shockwaves (integrated airbag and shock from Ridetech)
Anti-roll bar, not sure it has one from factory. Buick have steering at front of cross member other than torsion rods I don't see any other bars under there that would be an anti-roll bar
I understand more castor would create more turning camber, but what's intriguing is that there are no castor or camber adjustment shims on either side. I do want to do a castor review though. But again can only go on what alignment shop told me and they said in factory specs, I gave them the sheet below (from the shop manual) when doing so.
