2012 Boss 302 on square 305/30/19 RE-71R's at AMP - Graham MacNeil © For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear.

But being popular for track use comes with some headaches for manufacturers. It means that the car will be pushed hard by its customers and that will inevitably lead to discovering weak links . The vast majority of factory main-stream performance cars have limitations on track when pushed to hot lapping pace. That's not to say they are all equal - some are, without a doubt, far more durable and dependable than others - but nearly all require modifications. Mustangs are no exception. And their popularity also means those weak links are discovered fast, and marketing d
