I race on a 5/8 mile high bank track in the limited sportsman division.  We have an 80's buick regal.  We contantly get high temps on the outside of the RF tire but if we add camber the inside of the tire wears out right away.  We have been ignoring the temps for camber and just going by the wear.  Are we correct in doing so?

Thanks for the help.

Well, generally, the area of high wear and high heat are the same.  

What have you got for bushings in the front suspension?  does your car's body roll alot? what kind of tire and how much pressure do you run?

We use urathane bushings all around.  I would not consider it to be rolling alot.  we run 12psi in the left tires, 28 in the RF and 26 in the RR.  We notice this dramatically in the RF but a little in the LF too.

Thanks

Perhaps due to suspension geometry you loose camber really quickly when the suspension compresses, and with the extra static camber you burn  up the inside on the straights?  

I'm out of ideas...

btw, are these 10 inch goodyears?

We checked our camber gain along time ago and it was about 1 deg per inch but we have made changes since and should probably check it again.

Our tires are 7" American racers

Check right side square and RF ball joints conditions first. Center steering box, and check for toe in.
