Based in Wisconsin, the Ringbrothers custom shop is owned and operated by brothers Mike and Jim Ring. Their latest rolling work of art is this all-carbon fiber 1965 widebody Mustang Fastback "Espionage." The brothers handcrafted the carbon fiber body, which was widened by two inches on each side to create the signature widebody look. In addition to countless additional tweaks, the car's carbon fiber build is hidden underneath a flawless "Spy Green" paint job. Power, meanwhile, comes from a Whipple supercharged LS7 engine, good for 959 horsepower and 858 ft-lb of torque.
