Is it possible he didn't tighten something enough and my camber setting on the right rear changed?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

ok, so last year, when I had my winters put on the guys said my rears were shagged. Too much camber in the rear.
ok...
My summers were put in my tire totes and I didn't really look at them until today when I got my 2 new rears and was getting my stuff ready for going to the shop tomorrow.
As the photos show, the rear right has WAY more wear on the inside than the left. I don't have my alignment numbers in front of me, but I remember both the left and right being set at the same number. (maybe .1 difference)
The outside edges of both rears is worn about the same, it's only the inside.
Would that just be a bad camber setting? Is it possible he didn't tighten something enough and my camber setting on the right rear changed? Could this be something bent or broken?
Lying on the ground, my winters look ok, they are not nearly as worn on the inside edges, but they are much more narrow than my summer tires.
Any advice before I go to the shop tomorrow? He's a very reputable guy and does lots of work on sports cars in the area.
Photos attached....total mileage was 4500 Kms (with 3600 of those straight highway driving)

Less than 3k miles?? Looks like you were dragging it sideways.
Massive camber will wear the inside edge but usually not that severe in such a short distance, unless you can lay on the ground behind the car and see light under the outside 1/3 of the tire. I think toe is out also. Please post your "before" numbers when you get the alignment.
LOL, wife.....hell no!
I knew I would burn through them quick, I had been doing some drifting and general hoonery....smokey kind of stuff.
I don't recall hitting anything.
I will ask him to give me the before numbers tomorrow...

Your alignment is out. Probably to much toe in on the right rear. Camber is probably fine by looking your left rear it's normal to see more wear on the inside edge but that right rear tire is way off.
It might be alignment, but this could be it. When torquing up the rears on hard acceleration, the inside of the right rear takes the most torque. When I have worn out rear tires from hard track use, it had always been the insider right rear to go first and the rest of the tire still looking pretty good. That has also been true for a 3 series BMW I track.
you have a 4S though right? Do they have LSD in the rear or is it open? Even my LSD-equipped 40th does seem to wear out the back right more. Maybe that's just left-turn biased autocrosses though.
Ok, here are my alignment numbers. Before on top, final on the bottom.
Def the toe was out and so was the camber. Don't know if I hit something or he didn't tighten something all the way down. He did tell me the rear right was "fuzzy" to dial in properly. Not sure why that would be.
She's handling very nice again, but I would say some of that is just do to the nice fat summer tires.
This is very close to my after specs done at the dealer:
Front camber is now -0.3 both sides.
Front toe is 0.04 both sides
Rear camber is -1.4 both sides
Rear toe is 0.15 both sides
