Been using these on my track day Miata. My first impression was how little heat they require to get working. You can attack out of the pits better than on other lapping tires, and they don't suffer from heat as much as the autocross/time trial tires do. It will give up some time to the super 200 tw tires, but if you're more concerned with a consistent tire that can hold up to the abuse of 20-30 minute sessions, the Conti is excellent. Street manners are fine, not dissimilar to the other tires in the category. They suffer in the cold, and are ok in the wet. No real draw backs to this tire other than the cost.
