It took me three tries, but I finally found a guy that set my car to the specs I asked for and didn't cause any damage. The first shop was so far off my specs it wasn't funny. The rear camber measured -2.9° when I asked for -1.8°. The second shop over-torqued the nut on my SBC ball joint and broke it. They also cut a slit in the other SPC ball joint. I had to replace them both.
This last guy came highly recommended by the autocross crowd, so I gave him a try. It's not a fancy place, but he'll do it right and at a reasonable price. Check out
