ROUSH Performance is well known for their modified Mustang’s and F-150’s, but what few outsiders know is ROUSH Performance is the only company that modifies the Ford Mustang pre-title, making them a MOR, Manufacturer of Record. This means that they are held to the same standards as Ford, GM, Chrysler, and other OEM vehicle manufacturers. When the team at ROUSH decided to build the 850 horsepower TrakPak, they were a little shocked that they could build something that could pass emissions and still fit into a manufacturers guidelines! What better way to display its reliability and drivability than to take it on the best lifestyle rally, the goldRush Rally!
