(6 photos of a 2012 Performance White Boss 302R Mustang Coupe) Check this one out! It's a Performance White 2012 Mustang Boss 302R factory race car. This is not a street legal car - it was built for one thing - racing. 50 of these where built for the Continental Tire Challenge races. The base Boss 302R is equipped with a 5.0-liter, four-valve, V8 engine, a six-speed manual transmission, racing dampers and springs, a Brembo brake package, plus a roll cage, racing seat, safety harness, and data acquisition system. Another version has even higher performance, homologated for the Grand-Am Continental Tire Sports Car Challenge series, featuring a sealed, high-output engine with an upgraded cooling system, a close-ratio six-speed transmission with integral shifter, a high-speed-balanced, one-piece driveshaft, and a seam-welded body.
