yes cambered corners, again I didn't think of that. I am tuning my car for Winton racetrack and the roads around me, both of which are pretty much no camber. So perhaps level is the way to go in my particular case?

Your so right about the theoretical vs reality though, all this could make no difference at all.

I am going to see if I can reach under my car to put my digital angle gauge on the panhard.
