No, it's not because it's called Mach 1 or the heritage that comes with the name, although that's pretty cool for Mustang fans. There are few cars out there that have the widespread track use of Mustangs. A combination of affordability, a decent RWD platform with endless aftermarket support and the potential to be competitive when properly set up makes them a staple in most track paddocks in North America. 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...
