To much rear Neg camber?

I've had that problem on both E53's, and both times I replaced the upper control arms and that got camber back within spec.

The bushings were intact but had taken a set inward, pulling the top of the tires inward and causing negative camber.

I have visible neg. camber but no problems with wear, however since I just replaced all four tires i'm going to do the test where the spring pressure is removed sooner than later

Negative camber and toe in settings impact inside tire wear. Negative camber that is in spec is still visible and there is still inside tire wear. If the toe is taken out the handling becomes skittish. If the negative camber is removed turn in and max speed in a corner are reduced. Reducing negative camber will reduce inside tire wear. I think removing toe in takes the fun out of driving and passengers will be grabbing something to hang on.

Lowering, spacers and sometimes rim mods make it harder to get to alignment specs and more difficult to zero out negative camber because the suspension swing arm angle to the road is increased adding negative camber.

Changing spring rate and rebound of shocks could help but is very difficult to verify results. I don't think a better combination is enough to offset the compromise to ride and the majority of inside tire wear happens when driving in straight line.

I am not a fan of adjusting tire pressure because cold pressure and 'hot' pressure vary so much depending on so many variables. The exception would be if tires are filled with nitrogen.

IMO, If better tire wear is the primary goal adjusting out negative camber is the best option combined with tires that have a harder tread rating than spec with road force balanced tires filled with nitrogen.

That's some great feedback. I've always thought the neg. camber has got to beneficial for my "look ma, no brakes" style of cornering. I wore my last set of tires almost to the wear bars with no significant inside wear so I'm hoping my car and wife's are within spec and the bushing is not worn out. Her car needs new thrust bushings up front however it seems that hasn't affected alignment or tire wear to ny surprise
