Rear camber kit?

[Furlow]

I have a 2008 528i and the rear camber is driving me nuts. Had an alignment done, it's at -2.2 and the shop said they can't get it any less than that. I know BMW's are set up to have negative rear camber, but I don't like the look nor do I want to quickly go through tires.

I'm not finding many options for camber correction. One is these Godspeed arms which I ordered: https://godspeedproject.com/bmw-5-se...-bearings.html

A lot of negative reviews though for Godspeed in general so I'm nervous about putting them on. I also found these camber/toe bushings from ECS/K-Mac, but they don't say how much they can adjust: https://www.ecstuning.com/b-kmac-par...s/193726j~kma/

Any thoughts or ideas? Is there a "best" kit to get for this?
