Speedkore specializes in making carbon-fiber components and performance engines for Ford Mustangs. For a hard-core weekend racer with a Mustang, the company can provide a Carbon Series kit, including Mustang Shelby GT350 body and performance engine (worth 750 horsepower), performance suspension, brakes, radiator and a wheel-and-tire package. Speedkore also includes a Carbon Series interior with racing bucket seats and other goodies. All of this weight-saving goodness (the company does not say how much lighter, however) will cost you slightly more than $105,000, not including your donor Mustang. Visit www.speedkore.com.
