Rear Alignment: Relationship between Camber and Toe, Talking through my settings, interested in informed feedback! Options

[Morrie]

Hi Guys!

I had my car 4 wheel aligned yesterday and overall went well. I've replaced all the bushings, shocks, struts, springs, bearings, etc so it was all totally out of wack....

Good news, everything came into spec in front. All good. Car drives great now. In the rear I needed a bit of camber to clear the tops of my tires, so I am sitting here:

Rear Left:

Camber: -1 deg 24'
Toe: -0 deg 18'

Rear Right:

Camber: -1 deg 12'
Toe: -0 deg 02'

Camber: Factory says max difference from left to right is +/- 20'. I've got 12' difference side to side so I think I am okay there, even though the extra camber may cause some tire wear that I can live with.

Toe: Factory says toe should be 0deg +15' per side. The alignment shop set limits to 0deg +/- 15'.

A lot of numbers and I can make a bunch of guesses, but I would like to know for my road car which gets some spirited hill country driving, should I work on getting more positive rear camber toe, and is it as opening up the slots in the outside suspension arm mounts to allow for more rear travel of the arm?

Sorry if this is beaten to death or overcomplicated. Writing it down here helped me get it straight in my head. (IMG:style_emoticons/default/blink.gif) If it helps, below are my suspension settings and condition. Car was corner balanced prior to going for alignment, and is slightly lowered. Clearance on the RH side (passengers) rear tire is tight but it does clear with the current settings.
