Alignment with soft lip wheels?

[formula]

Hey guys,



I'm just getting ready to move to a more agressive alignment, and this is the first time I've had to think through the difficulties of having a shop do my alignment with my forgelines. As I recall, my favorite shop uses equipment that attaches to the wheel lip normally-- does anybody know what sort of gear is out there that won't risk wheel damage? I live in a very small town so I know that unless I keep an eye out for the right gear, they'll just "engineer" something.
