SARD (Sigma Advanced Research Development) is a company and race team in Toyota, Aichi, Japan specializing in Toyota parts and vehicles. Back in the ’90s they built several race cars based on a Toyota MR2 SW20 called the MC8-R for Le Mans and Super GT. They were powered by a twin-turbo 4.0 L 1UZ-FE V8 estimated to make 600 horsepower (447 kW). It competed from 1995-1997 but did not have a very successful career. To comply with homologation rules at the time, SARD built one road version of the race car in 1994 called the SARD MC8. The road version features lengthened chassis supporting a 4.0 L 1UZ-FE V8 mated to a Porsche six-speed manual transmission with a Tilton clutch. The body is a mix of steel and custom dry carbon fiber panels. It stops thanks to Supra A80 disc brakes behind SARD 18-inch wheels. Update 5-29-19: Owner has an Instagram for car.
