I seem to recall that max lateral G's of friction is 1 G, and that to go above that adhesion is required.

If true I interpret this to mean that typical street tires would be limited to 1.0 G.

Am I nuts, close, or correct?

I have seen street tires go over 1g. Just look at what Danny P did. The track was not completely dry either.

those results were done on a 2 lap average and one of his lap was above 1.12. On street tires that had seen 4500 miles of use.

A little off-topic, but I found it interesting that a Viper and a Vette scored below a Grand Cherokee (24th place)... (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

On topic, I think one factor is going to be the interaction of irregular surfaces. The rubber can deform into pits/crevices in the track surface and create a bit of a shearing effect on a small scale.
