The Netherlands Carburettor only Normally aspirated Cast iron block BriSCA Formula 1 Stock Cars is a class of single-seater stock-car-racing in the UK with custom-built cars, with races conducted on walled oval tracks of either shale or tarmac of approximately a quarter-mile in length.

The cars follow open wheel design principles, and there are no horsepower restrictions for the engines.

Rules and regulations relating to car specifications, race procedures, track requirements and all other aspects of the sport are updated annually by the BriSCA Management Board.

BriSCA F1 Stock Car racing can trace its roots to the first stock car race in United Kingdom, which was held at New Cross Stadium in London on Good Friday, 16 April 1954, promoted by a Northampton-born Australian showman called Digger Pugh.

The cars were standard makes with wheel arches removed, and with bumpers added along with roll bars.

[1] In 1957, thanks to the efforts of Peter Arnold, a national numbering system was introduced, BriSCA, the association of promoters was formed and the Stock Car Racing Board of Control created.

In 2019 the Spedeworth V8 Stock Cars separated from all racing governing bodies and became an outlaw group.

In 2023 the sport has seen the addition of new drivers moving from the BriSCA V8 Hot Stox formula to the V8 Outlaw Tour.

Currently BriSCA F1 are governed by the British Stock Car (promoters) Association, ORCi, and Spedeworth International.

A modern BriSCA F1 configuration is front-engined, rear-wheel drive, and open-wheeled, with the driver located centrally.

Power is most typically delivered through a 'Doug Nash' style gearbox with two forward gears (one for racing) and reverse, and use a heavily modified Ford Transit rear axle with a locked differential.

BriSCA F1 Stock Car races are normally held on short, approximately quarter-mile, oval tracks, either tarmac or shale.

Drivers' scores at every stock car meeting were recorded to create the championship table.

During the late 1990s, when Frankie Wainman Junior dominated, there was criticism that the National Points Championship was predictable and favoured drivers who had the money to race at as many meetings as possible.

Rather than the points accumulated over the entire season counting towards the winner, the National Series was competed for over 35 designated meetings.

The drivers raced over ten designated shootout rounds, with the points scored in them deciding the winner of the National Series.
