Just had my car outfitted with some Hoosier tires, and can't believe the difference. With the Goodyears my car would become unstable in second gear at about 5000 rpm. The rear end would break adhesion, and the front end would turn left as the rear end came around. I have noticed on some of the videos on the forum, that this has happened before. This is apparently caused by the enormous torque that this engine develops at higher rpm. With the addition of these new, stickier tires, with a groove cut in them to make them legal, my car does not break loose as it did with the Goodyears. True, these tires will not work in the wet. But I don't plan on driving in the rain, too much cleanup afterwards. Bottom line is, now I can drive around my area and jump on it once in a while, and not feel that horrible feeling that a loss of control gives you. These are all my opinions, and hopefully can help everyone with additional knowledge.
