I f I get a supercase and iron midpalte will my M20 have any change in a street driven 496 car?? No abuse, just a show car and it has stock 14x7 tires. What are your thoughts, or do I go T400 right away?
Our M20 has stood up behind the L72 motor for the best part of 200K miles. I never ran slicks, which will quickly find the weakest points, but I did run some pretty big rubber on the back and leaned on the car fairly hard lots of times.
