Positive Camber Impossible?

Oh it's definitely worth being careful. Most of the techs at alignment shops nowadays have no idea how to deal with one of these cars. Having them follow the factory procedure correctly would be outstanding, even if it would result in the wrong alignment for radials. But most places you won't even get that. That's why I bought all the tools to do my own alignments. Well, that and the fact that most shops won't put a "custom" alignment on a car, even after you explain to them that using the factory numbers "in the computer" will result in a poorly handling car because the factory specs are for bias plys and are completely the opposite of what radials should have.

And yeah, "jouncing" doesn't work, the car has to roll to settle things out.
