In 1975, about 30 southern based drivers broke away from BriSCA and formed their own association called SCOTA (Stock Car Oval Track Association). They were disappointed at the lack of F1 meetings being held in the south of the country. They raced for promoter Spedeworth in cars exactly the same as BriSCA F1. In 1978 it was renamed F1SCA (Formula One Stock Car Association). In 1980, F1SCA decided to introduce a five-litre limit, and make the cars slightly smaller. Renamed 'Formula 80' the cars are still running today under the name 'Spedeworth V8 Stock Cars'.
