Raceparts Historic 750 Formula

The 750 Motor Club’s ‘Historic’ racing series, for cars built to early eras of 750 Formula regulations. Primarily comprising Austin Seven Specials and later Reliant-engined Formula cars, new cars have to be built within careful guidelines to ensure compatibility and enquiries from other historic cars of a similar style are welcomed.


Engine

The range includes Austin 7, Reliant engines (642cc and 748cc OHV, 747cc side-valve), Ford 1172 side-valve and Climax; F3 500cc class must comply with 500 OA rules.

Suspension

This varies a lot dependant upon the class in which the car runs. It can be anything from leaf springs through to ‘coil-overs’.

Brakes

In the Austin 7 classes, brakes are restricted to the Austin 7 drums. In the other classes, the use of disc brakes is not permitted unless part of the original design.

Transmission

Classes A & B must use the standard A7 casing; alternative ratios may be fitted, either 3-speed or 4-speed, plus reverse.

Tyres

Class A restricts width and profile; classes B & C now use an affordable historic control tyre to equalise performance, available both new and secondhand.

Rounds

There are 12 rounds in the 2018 season, spread across six ‘double-header’ race weekends.

Costs

Club membership is just £25 for 12 months, season registration is £85, and double-header weekend entry fees (qualifying and 2 x 15min races) are typically between £240 and £340 depending on the circuit. Eligible cars are available secondhand from just £3500.
