About the FR500S

The Mustang FR500S is the newest addition to the Mustang FR500 race car family.

Manufactured at AutoAlliance International in Flat Rock, MI -- the same facility that builds street-legal Mustangs, the limited-edition FR500S is the first race car built by Ford Motor Company on a production line intended for sale to the public. The car features the 4.6L 3-valve production V8 engine and a variety of Ford Racing performance parts, including a cold-air kit, high-capacity radiator and two-way adjustable dampers and springs. The car can be ordered through Miller Motorsports Park or your local Ford dealer and is delivered to the customer in race-ready condition, complete with a roll cage, racing seat and safety harnesses, an AIM data acquisition system and even a timing and scoring transponder.
