I just took the first 25 miles or so by chance on my way to Memphis last week and this road rocks. Hill's, curves, and little traffic (at 7am on Wednesday morning anyway). I have no idea what the road is made of but it is red, like a clay tennis court, and the GT's just loved it. They were really sticking and it was only an hour or so after a rain storm. However then I turned south on 95 and that is one nasty road that some of the Avon folks might like as it gets real nasty.
