Here is my 2011 Roush stage 3 Mustang. The car was purchased directly from Roush Performance. Its life began as 2011 development vehicle for Roush. They changed the hood, front end, and rear end to look like a 2013 and then dropped in the forged Ford Racing Aluminator block and added the Roush Phase 3 supercharger kit. It has all the other Roush goodies like suspension, brakes, and exhaust. The car is awesome. Only issue is traction!
