Do you have a price range in mind? What is your application: street, autocross, DE, over the river and through the woods to grandmother's house, a bit of each?

Primarily street driving, with a little fun cornering now and then but nothing terribly aggressive. The Toyo's are running $150ish for the fronts, $170 rear.
My PS2's are just about done and after doing some research I've decided to go with Dunlop Direzza Star Spec tires. The price is good and they are a better tire for autocross/track use than the PS2's. If you are looking for a long wearing all season tire this tire wouldn't apply, but if you want a lot of grip in a street tire then look no further.
