Alignment experience
This is both a report of alignment noodling and a question....
With staggered setup (235f, 255r) we've found the sweet spot for our car to be as follows:
Front:
zero toe
camber -2.9 ish
caster factory
Rear:
1.2mm toe in each side
camber -2.4 ish
Based on the day/track, have been playing with rake and bar settings (often just adjusting 'half a hole') to get the rear end to stick better on turn-in.
Ran data yesterday with shock sweep settings and... well, that's another story (PSS9s are... sh*t).
Here's the question...
Changed the alignment yesterday to run just a wee bit of toe out on the front and increased the rear camber to match the front, i.e. -2.9 ish all around. Front bar half a hole off full stiff and the rear bar at full soft.
Ran on scrubs and was 0.8 off my PB (mosport) on fresh tires. Car was a handful to drive with a lot of mid corner push. More twitchy *** wiggle than I like at turn-in. Once the car took a set, I think the increased rear camber gave the rear end too much grip at mid arc. Too much rear camber??
Thoughts? Experience?

I tell you what, when you get to Jersey I'll set your car up for you. You just get a good night's sleep. Don't worry about a thing 
To actually answer your question I run square with .5 degree more neg camber up front than the rear and either zero or a wee bit of toe out up front. I only have the front bar so it's either set in the middle or one from full stiff depending on the track.
I have not played with any other set ups. Interested to hear your experience and from others.
