For what he's doing, the camber change won't be significant enough to require an alignment. He'll only do it 2-3 times a year and the small amount he raises it will only cause a small amount of change in camber. Camber being slightly off will affect tire wear a very small amount, you'd have to go thousands of miles to see a wear problem and even then it would be isolated to a small part of the tread. If his alignment is already skewed towards max negative camber, raising the car and losing a little bit of negative camber will actually make his car safer for his runs in the hills by making the car more likely to understeer initially which is easier for the average person to deal with at the speeds he'll likely be running. Actually, I'd be surprised if he got 1/2 degree change in camber by raising it 1/2", the +/- in the specs is more than that. The camber curves are excellent also, most of your camber gain in corners is from caster anyway which is what you want.

Let the toe setting get a little off and you'll wear out a pair of tires pretty quickly. Let toe get more than a little off and watch the tires get shredded in literally hundreds of miles. I've run negative 2 degrees of camber on the street for a long time with minimal wear to the inside of the tire.

 

Just have it checked to be sure! It just takes only a couple of hours and then you will know for sure.

 

glass slipper, care to comment on this thread?

it seems to indicate that the c5 doesn't have what i would consider close to zero bump steer.

 

glass slipper,

still trying to get to the bottom of this. here's another new thread in the racing section http://forums.corvetteforum.com/auto...-geometry.html where the guy measured 1/4" total toe change over 2" height change. seems like an awful lot to me.
