Rung 2 of the Caterham Motorsport ladder is a closely fought full race championship, in identical 500kg, 120bhp machines. Team support is not allowed, to keep costs to a minimum.
Following on from the Caterham Academy series (a series restricted to only those who have never held a competition licence before), Roadsport allows an easy upgrade to the car to improve lap times, chiefly through the use of Caterham specific Avon CR500 tyres. The car remains road-legal.
As with all Caterham racing, the tight technical regulations ensure a level playing field of cars.
Race meetings are all double-header rounds of 20 minute races.
With no team support allowed, every round is supported by the Caterham Midlands race centre, which competitors can elect to contribute to, providing them with central support.
