750 Formula Championship

The oldest continually running race series in the world (older than F1), 750 Formula is believed by many to be the ultimate in fun, low cost racing. As the most affordable 'slicks & wings' racing in the UK, these are sports-prototype racing cars with an offset driving position and small passenger space, lapping with times that defy the budget involved at all circuits. Many cars have been individually designed and built by enthusiasts over the years but there are also kits available.

Engine

The formula uses the reliable Fiat 1108cc ‘FIRE’ engine in fairly standard trim to keep costs down and reliability up, with a control camshaft to regulate performance. Tuning is largely restricted to balancing the engine, lightening the flywheel and skimming the head. Induction is restricted to one carburettor choke while the exhaust system is free.

Suspension

Design is free, but cars must either use a live rear axle, or a FIAT transaxle complete with the standard five-speed gearbox/final drive and independent rear suspension.

Transmission

Four-speed plus reverse or five-speed if using the FIAT transaxle. Limited-slip differentials and all forms of traction control are prohibited.

Tyres

The formula uses control slick tyres which tend to last the best part of a season and are often available second hand. Competitors at the sharp end of the grid will probably use 1.5 sets per year, and wets are free.

Rounds

There are typically 12-14 rounds in a championship season, spread across double-header and triple-header race weekends.

Classes

There is an additional 'Class B' for drivers who have not finished on the podium, in the top six in the main championship or won the Class B Championship in the last five years. Trophies are awarded for the top three finishers in Class B as well as the main results.

Costs

Club racing membership is just £95 for 12 months, season registration is £140, and double-header weekend entry fees (qualifying and 2 x 15min races) are typically between £340 and £420 depending on the circuit and whether double or triple-header. Cars can be bought secondhand from approximately £5000.
