Mk4 Challenge Model
The Factory Five Challenge model is the competition version of our best selling Mk4 Roadster. The car is designed for hard-core racing junkies. With the Challenge car kit, you’ll be ready to compete safely in auto-cross events, drag racing, road racing, rallies, and all forms of amateur racing.
If you are a person who plans to use your car for more than an occasional open-track day, then this chassis kit was designed for you. Built from the foundation of the proven Mk4 chassis, the modified challenge car chassis meets SCCA GT1 design criteria and is approved for NASA’s Factory Five Racing Challenge Series.
Challenge Cars have been dominant in racing classes across the country for more than 10 years. Ford Racing selected a Challenge Car to serve as one of the 2006 Champ Car “Fast Laps” car. Challenge cars have earned top spots in local and national level SCCA and NASA roadracing series.
Factory Five Racing sponsors the NASA-FFR Challenge, where spec-built challenge cars race each year towards regional and national titles. Major changes in Challenge Series rules have become effective for 2012 and this website is being updated to give you current information.
