Fantastic tire. Very, very sticky in the dry. If your temps are near 40F, they're just blocks of rubber; but you already knew that if you're researching summer tires. An astonishing amount of grip in aggressive off & on ramp and back roads carving. Haven't taken the car to auto-x yet with the tires, but I'm looking forwards to it since the street driving hasn't been anything but rewarding so far. Looking forwards to seeing how quickly I can find their limit on the course.
