context_page_description: Grand-Am Road Racing or Grand-Am was an auto racing sanctioning body that was established in 1999 to organize road racing competitions in North America. Its primary focus was the Rolex Sports Car Series, an endurance racing championship series. It sanctioned five auto racing series. The series announced in September 2012 that it would be merging with the American Le Mans Series, which had been Grand-Am's main US competitor since its inception. The two series fully merged in 2014 under the banner of the TUDOR United SportsCar Championship, with the International Motor Sports Association.
context_section_description: The Ford Racing Mustang Challenge for the Miller Cup was a series which started in 2008. A one-make series similar to the Ferrari Challenge, this series used identical Ford Mustang FR500S cars co-developed by Ford Racing and Larry H. Miller, owner of Miller Motorsports Park. The series featured amateur drivers in 45 minute sprint events.
  The series held its final event September 12, 2010 at Miller Motorsports Park. In the announcement, the series predicted that the FR500S Mustang "will continue to be eligible for competition in a variety of series." The FR500S chassis are now eligible for competition in the GTS class of the SCCA Pro Racing World Challenge, with several modifications to bring their level of performance equal with the other cars in the class. Six Mustang Challenge competitors entered their first event as GTS cars at the Mid Ohio race August 7 and August 8, 2010.
