Warning! Science Inside! Tire Friction Coefficient

[ccracin]

I'm sorry to get all technical but I am curious. Has anyone found or determined an average coefficient of friction for the typical performance street tire alot of us are using on our vehicles? I have done some research and it seams published figures are in the neighborhood of .7 to .85. This doesn't make sense in that 1g plus of cornering force would be difficult if not be possible on "Street" tires if this is the case. Has anyone recorded 1g+ on "200 Treadwear" tires? If not what is the highest you have seen? Another way of looking at it, is has anyone recorded -1g or greater in braking?

This is really where I am interested. I am playing with picking brake components and have found some interesting things along the way. There are so many factors that affect brake balance it is staggering. So let's hear it, anyone have real numbers?
