NASA Announces New Spec Iron Class.
NAPA VALLEY, CA (January 14, 2013) The National Auto Sport Association (NASA) is pleased to announce the introduction of a new class that will join the American Iron® series of ponycar racing in 2013. This new class will provide a lower barrier of entry to the series and complement the existing American Iron (AI) and American Iron Extreme (AIX) classes with an “American Iron Spec” type formula. The new Spec Iron (SI) class will feature the 2005-2010 Ford Mustang GT and is supported by Ford Racing. The cars will use a number of parts specified from the Ford Racing catalog along with the Toyo Proxes RA-1 tire following the successful formula that NASA has applied to many other spec classes. The “spec” prep level of the class will ensure that the class is a “driver’s class” full of close competition, limited modifications and exciting racing.
