Holy cow.. that's a pretty bad method to get more negative camber. If you fail to bang it back to an acceptable position, or damage it in the process, a skilled welder should be able to fix it for you I'd think. Worst worse case, the rear subframe can be replaced.

I had this same issues with my car that is lowered on Koni Yellows and Eibach Pro Kit. I was told that I needed "Ball Joints" and that should fix the alignment. I never got it fixed yet lol.
