The Ford Mustang FR500S embodies a rich racing heritage dating back to the days when Parnelli Jones, George Follmer and others drove Bud Moore-prepared Mustangs in hand-to-hand combat battle with Mark Donohue, Dan Gurney, Swede Savage, Sam Posey and other American icons in the original Trans-Am Series. Not for nothing was an entire class of sedans-come sports cars known as “pony cars.”
In honor of that heritage, Ford Racing and Miller Motorsports Park developed the Ford Racing Mustang Challenge, a professional, single make series utilizing the Ford Mustang FR500S, sanctioned by the Grand American Road Racing Association and running in conjunction with top tier professional road racing events throughout North America. With its competitive points structure and lucrative purses, the Mustang Challenge is an affordable arena for emerging and established professionals seeking to compete in a V8-powered, rear-wheel-drive car on a level playing field showcasing driver ability.
The Mustang FR500S is the first race car built on a Ford production line that is sold to the public. Built in Flat Rock, MI on the same production line as other Mustangs sold to the public, the FR500S is then sent to Watson Engineering in Taylor, MI for additional race-prep fabrication (including the installation of roll bars, etc.) before being shipped to Miller Motorsports Park in Tooele, Utah for final race prep.
The FR500S features an aluminum 4.6 liter, V8, three-valve production engine rated at 325 bhp, together with a variety of Ford Racing performance parts, including a cold-air kit, high-capacity radiator, aerodynamic package and two-way adjustable dampers and springs, plus BFGoodrich g-Force R1 tires. The Mustang is equipped with a six speed Ford Racing Tremec T6060 transmission, clutch and short-throw shifter, as well as Ford Racing/Borla stainless steel headers. The FR500S features rack and pinion steering, Ford Racing/Brembo ABS brakes, two-way adjustable front dampers with coil springs, adjustable anti-roll bar and adjustable ride height. Rear suspension is live axle; Panhard rod, two-way adjustable rear dampers with coil over springs, anti-roll bar and adjustable ride height.
