The Grand Am GT RX-8 is based on a tube-frame chassis jointly developed by SpeedSource and Riley Technologies and powered by Mazda's three-rotor 20B rotary engine. A turnkey GT racer from SpeedSource will start at $280,000 and include chassis, full drivetrain and engine management system, suspension, wheels, tires, and bodywork.
Mazdaspeed will also carry the Downing/Atlanta carbon-fiber body panels and the 20B racing engine on a made-to-order basis. It says it will "offer a lucrative contingency awards program for the RX-8 in Grand-Am GT for the 2006 season."
