Monoposto Racing Club

The Monoposto Racing Club (MRC)^[a] is a single seater, open-wheeled motor racing club in the United Kingdom. Its members race a variety of single seater race cars ranging from 1000cc "Mono Moto" cars to 2000cc Formula Three and Formula Renault cars.

Monoposto Racing Club has been in operation since 1958.^[1]

As of 2010, it is the largest single seater championship in the UK, with over 60 regular race entrants.

The aim of the club is to organize single seater racing for the club racer.^[2]

The Monoposto Championship is organized by MRC. It visits most major UK race tracks, including Silverstone GP, Brands Hatch GP, Snetterton Circuit, Donington Park GP, Oulton Park, Castle Combe, Pembrey and Rockingham.

It used to have an annual non-championship event at Spa-Francorchamps but rising costs lead to this being cancelled. The club also runs the autumn Tiedeman Trophy Championship, named after the club's founder Frank Tiedeman, who died in 2013. Occasional non-championship rounds are also run.

Points are scored for all finishers in their class order, with 15 for winner down to 1 for 12th and below. There is also a point for fastest lap in each class. Invited drivers are not eligible for points.^[3] The championship is decided from the best 10–12 scores from around 12 to 14 rounds. Events are generally run over 2 days with 4 track sessions per grid. This may be a separate qualification and race each day or a single qualification session and 3 race sessions.

Production chassis must be at least four years old, except for homemade chassis.^[1]

It has several classes of cars, starting with "Mono": Moto 1000, Moto 1400, 1600, 1800, 2000 Classic, 2000, F3 A and F3 B; these are based primarily on the maximum permitted engine size, but also engine tuning freedom, chassis age and chassis materials. Most race meetings have the classes spread over two grids, with the 1000 and 1400 cars on one, and the 2000 classes on another. The 1600 and 1800 classes are alternated between the two, either together or independently, depending on the circuit and expected entry numbers.
