I thought there would be a thread about this somewhere as well, but it's good to revive the subject anyways. That's a good thread on zilvia, it's the one i was referring to earlier.

That's cool about the math thing, I was thinking about it, and came up with some sorta crappy equation lol. The pivot point of the wheel with camber is offcenter (referring to the control arm's connection with the spindle), but how much is it off? it looks to be roughly 70% the distance from the top of the wheel. If referring to only the wheel height, which i imagine is what a lot of people go for as far as the whole tire stretching thing goes, that would make things relatively easy. But since tire sizes vary so much, everyone would have to measure their tires to get a good reading... Here is sorta what I came up with:

(.7 T x 3.14 x 2)
360

Where T refers to tire or rim height, that finds the distance that X amount of camber would move the wheel in at the top by simply multiplying the product by the degrees camber.

But what's hard about that I suppose would be finding a base mark to go off of. I would think somewhere around a 17x8 +25, 17x7 +13, 17x9 +38 would be nearly perfectly flush with 0* camber on the front, but i am not certain since I haven't seen it... Plus front and rear clearances are different, different tire brands have different size tires and varying widths for the same sizes. lol, lots of variables to consider... I just thought i would put in my .02 in on it, and hopefully help in the development of the equation that will end wheel flushness questions until pigs fly
