As the most modified car in the world, there’s no shortage of aftermarket goodies for the Mustang. The best of these tend to come directly from Ford
who provide all the right bits to make the car quicker and more drivable, all of which come with a warranty.

But Drive’s Matt Farah thinks Roush has delivered something even better with its Stage 3 Mustang.
