Yep, toe out is much worse for tires. I'm running -35mm vogtland's and rear right is -2.18 degrees. Not bad, but would be nice to get it better. I will probably modify the original bolt and adjustment to make it little bit better.
I just fixed the loose end's from the rear. Rear upper control arm's were shot and also the lower ball joint. Basic E53/E38/E39 stuff.
