Hi, I can't seem to find a shop that will do an alignment on my car with the 19" rims for whatever reason. THe negative camber is very noticeable, especially in the back. I realize it wouldn't be the precision adjustments that a real alignment would give me, but is there anyway i can make some crude adjustments with the back end jacked up, at least to the point where the negative camber isn't so bad? Its got to be at least 5 degrees or more of negative camber right now, and i think its really hurting my traction, not to mention wearing just the inside of the tires.

Any help is appreciated!
