The most affordable 'slicks & wings' racing in the UK; these are sports-prototype racing cars with an offset driving position and small passenger space. Many cars have been individually designed and built by enthusiasts over the years but there are also kits available and a good second-hand market. The regulations are designed to encourage close, competitive racing while controlling costs, and the cars are lightweight with excellent grip and balance. The oldest continually runing race series in the world (older than F1), 750 Formula is believed by many to be the ultimate in fun, low cost racing.
The formula uses the ultra reliable Fiat 1108cc ‘FIRE’ engine in fairly standard trim to keep costs down and reliability up and with a mandated cam to even out performance. Tuning is 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. All this gives a power output of around 95-100 bhp and a nice wide power band, which, combined with the light chassis weight, gives average lap speeds of 85-95mph, making the cars a second or so off the BTCC lap times at most circuits.
Design is free, but cars must use a live rear axle, or a FIAT transaxle complete with the standard 5 speed gearbox and final drive and independent rear suspension.
Choice is free.
4-speed plus reverse or 5 speed if using the FIAT transaxle. LSD and all other traction control is prohibited.
The formula uses control Yokohama slick tyres which tend to last the best part of a season and are also available second hand from the Sports2000 formula. Competitors at the pointy end of the grid will probably use 1.5 sets per year with tyres costing around £475 per set fitted. There is a Yokohama service truck at most race meetings. Wets are free.
There are 12 rounds in the 2021 season, spread across six 'double-header' race weekends. The best 10 results count for the championship.
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.
Club membership is just £25 for 12 months, season registration is £120, and double-header weekend entry fees (qualifying and 2 x 15min races) are typically between £260 and £350 depending on the circuit. Cars can be bought secondhand from approximately £5000.
