Maybe if you drive in a straight line all the time. I run ~neg 2 degrees on the M3 and -1ish on my accord. They might show some excess inside wear after maybe 20k miles…
I wasn’t sure if you could do the washer trick on the rear control arm like I did on my Accord, but if it makes you feel better you can zero out camber in the rear and swap tires front to back to reduce the wear…but I really don’t think -1 to -2 camber will give you problems if your toe is zeroed out.
