Series: GRAND-AM Continental Tire Sports Car Challenge
Driver(s): Billy Johnson, Jack Roush Jr., Shelby Blackstock, Joey Atterbury

The Roush Performance Boss 302R runs in the Grand Sport (GS) class of the CTSCC. It won the 2013 season opener at Daytona -- no small feat, considering that it ran against the likes of Aston Martin Vantages and Porsche 911s.
