This October, AmericanMuscle's Hot Lap takes you behind the scenes at the Roush Performance headquarters. We bring you along on a test drive of the powerful 2015 Mustang RS3 from Roush and put it through its paces. After a look at the facility, we get hands on and help build a Roush Supercharger system on the assembly line. Interested in checking out the Roush Museum? Their collection of Ford Mustangs is unreal. Make sure to subscribe to AmericanMuscle.com on YouTube for that video dropping really soon.
