These are a junior version of the adult specials, with a full space frame chassis, some made from "used" adult cars, but ALL cars must use the Vauxhall Corsa 1200cc engine, plus specified Vauxhall gearboxes, original style struts and driveshafts. No engine or gearbox modifications are allowed, apart from some basic reconditioning.
With cheap donor cars plentiful and older chassis easy and cheap to come by, this can be a very economic option. The engines and frames can last an entire four year racing career!
Professionally constructed cars are also available ready built or in kit form. Drivers of these cars must be between the ages of 12 and 16 years, although adults can drive these cars at single day club meetings.
