These tires came stock on my 2011 Mustang GT/CS. TO call my driving style spirited is an understatement. I am an auto-crosser. I have not auto-crossed the Mustang, but I enjoy the car daily on the back roads and highway to work. Handling, acceleration, braking, and overall performance were exceptional. I am down to the wear-bars on all four tires at 18,000 miles, but I am happy with that longevity considering what I have asked of these tires. For the price, these are worth the investment as a performance street tire. I would want more lateral grip if I were going to run this car on a track or in autocross. They are predictable when they do break loose, and easily re-grab traction to gain control of the car.
