I am currently running the Conti ExtremeContact Sports 2. This is my second set. Great for touring, Autocross and HPDE.
The Contis do not have the grip of my old Hoosiers (duh) or even the Toyo R1R's (that I have used previously) on the track. The Contis offer a nicer ride and almost as good for the track days.
If you are in the Portland Oregon area, I recommend you see Garth at Trackside (aka AnT Tires) on N Interstate. Knowledgeable guy, good prices.
