This 2008 Ford Mustang FR500S is a track-only model designed by Ford Racing and Miller Motorsports of Grantsville, Utah for competition in the Ford Racing Mustang Challenge spec racing series. Chassis #072 was reportedly used as a display vehicle at Miller Motorsports Park before being acquired by the seller in 2018 with less than 150 miles. The car is finished in white with red and blue livery, and power comes from a blueprinted 4.6-liter V8 paired with a six-speed manual transmission. Additional equipment includes a roll cage, adjustable dampers, an aerodynamics package, and more. This FR500S is offered with a Michigan bill of sale. The FR500S featured an aerodynamics package similar to that used on the contemporary FR500C Grand-Am cars, including a splitter up front as well as a wing and diffuser in the rear. Polycarbonate quarter and rear windows contributed to a curb weight of approximately 3,400 pounds. This example is finished in white with red and blue stripes, 572 numbering on the hood and doors, and sponsorship decals. A paint blemish on the hood and scratch on the right rear wheel arch can be seen up close in the gallery below. Ford Racing 18″ wheels are mounted with BFGoodrich tires. The FR500S featured adjustable sway bars, stiffened springs, two-way adjustable Sachs shocks, and a Ford Racing steering rack. Braking is provided by four-piston Brembo calipers and 14″ slotted rotors up front, Shelby GT500 disc brakes out back, and a four-wheel anti-lock system calibrated for track use. The stripped cockpit features a single Sparco racing seat with a multi-point harness, a roll cage with door bars, a window net, a quick-release Sparco steering wheel, an AiM MXL digital display mounted to the steering column, a branded toggle switch panel in the center stack, and an engine-start button. Just under 150 miles are shown on the odometer. The 4.6-liter V8 was shared with the contemporary Mustang GT, but was dyno-tested and sealed by Roush Industries for installation in the FR500S. Modifications include a recalibrated PCM, an 84mm cold air intake, and Borla long-tube headers feeding a Ford Racing exhaust system with an X-pipe. A new Motorcraft battery was installed in 2019. A Roush Industries engine sign-off sheet dated October 2007 can be seen in the gallery. Power is sent to the rear wheels via a Tremec T6060 six-speed manual transmission, a heavy-duty clutch, and a 3.73:1 Torsen limited-slip differential. Fluid changes and an inspection were reportedly carried out by Capaldi Racing of New Baltimore, Michigan in 2019.
