March Engineering
The Dome RC83 was a Group C sports racing car built by Dome in 1983. A replacement for the RC82, which had been unsuccessful in its two 1982 entries, the car featured a 4-litre Cosworth DFL V8 engine and was developed in-house, unlike the RC82, which had a March Engineering chassis. One car was built. The car was replaced by the Dome 84C partway through the 1984 season, although the two cars did overlap during that year.
