Unusual wearing of passenger front tire
When i purchased the vehicle a couple of months ago and got a PPI from the Mercedes dealership they did not note any issues with the bushings but i'll have them check it again when they get it on up on a rack.
Toe does indeed change the feel dramatically. I'm running +.03 at the moment and love the feel. .15+ (Factory spec) was a bit sluggish on the steering I felt.






But I am not sure I buy this:
AMG3.2's camber pic is a great illustration of wear from excessive camber - clearly the OP's problem is more than just camber.
But I am not sure I buy this:
On our negatively cambered cars, the wear is always going to be worse on the inside edge. Excessive toe (in either direction) makes the wear worse and the direction of the feathering is what provides the clue as to toe out vs toe in. Make sense?
