tire pressure?

Up to a point that is true. However, if you run more negative camber, it will not work.

I personally run 3/4 degree negative camber so it corners better. The spec calls for 1/4 degree for street, and 1/2 to 3/4 for competition. I pay for that in tire wear, but figure it's worth the trade off.

Then you average. For example from outside to in....109-114-119 degrees would be perfect for running more negative camber. Now if the temp was 109-125-119 then I would drop 1 psi at a time until I get a nice average. If the temp was 109-100-119 I go up just 1/2 psi at a time until I get that nice average. Just remember with more negative camber the inside will always be the hottest.

McDOO,

Do you do this(take temps) immediately after you session? Or do you have people waiting in the pit area to take the temps? It seems like your tires could cool some by the time you get back in the paddock area.

Thanks in advance.
