Factory Five Challenge

NASA and Factory Five Racing (FFR) formed a partnership to create a unique class based on the widely popular Factory Five Racing 427 Roadster platform. Factory Five Racing has built a purpose-built spec racer, which is based upon their FFR 427 Roadster with an integrated roll cage. The Factory Five Challenge spec racer uses Mustang 5.0-liter running gear, and provides the perfect combination of performance, safety, affordability and good looks. Additionally, this car is built for race competition yet remains street legal. This is the ideal class for a person that has always wanted to own and experience the true performance of an FFR 427 Roadster both on the street and on the track!
