The series was for Group C cars which fit into the smaller, less powerful, and cheaper C2 category.
This was also aided by the fact that there were already several British teams running C2 class cars on the international circuit.
Although only seven cars would attend the opening race at Silverstone Circuit, the series was able to expand to sixteen competitors by the end of its first year.
1990 saw the series suffer even more as most races averaged nine competitors, some of which never even made it to the green flag.
A national sports car series for Britain would not return until 1993 when the BRDC GT Championship was created.
