Neg 2 rear camber on stock suspension

[brokenboosted]

Hey there!
Getting new tires tomorrow and I know my rear camber is crazy out of spec because it eats tires on the inner edge very very quickly. did an alignment at firestone (lifetime alignments) and got some strange results.
First off they really wanted to shoot for 0 toe all the way around but said they got it close as possible but seemed to complain about it for some reason.
Second off the whole reason I took it there was to fix the rear camber which they didn't even touch on one wheel and nudged on another. They tried to say 2 degrees is in spec even though the sheet doesn't even say that. there's no way because the wear is super fast.
It can be adjusted more positive than that right? nothing appears to be worn of bent and it is both rear tires. Rear left wears slightly faster I noticed

I sold mine I didn't need them after lowering my car. sounds like your car has some possible linkage bent or worn.

if you wish to double check me go to spc manufacturing website. I bought them from summit cause they made sure I got the proper Ford parts. my research indicated they fit all our years.
