The Superlight R300-S Championship is the pinnacle of Caterham Seven Motorsport and our flagship series. It delivers more power, more speed and more competition.

Launched in 2009, the R300-S provided a stepping stone between the then Roadsport-A category and the R400. However, the R300-S proved to be such an easy and rewarding car to drive, that the lap times came close to that of its much more powerful stablemate and it quickly became the premier Caterham series. The philosophy behind the R300-S is to provide a step in performance without making it necessary to have team support. The suspension on the car has fixed rate springs and dampers, like a Roadsport, reducing the need for testing and simplifying car set-up – both of which help ensure the level playing field of competition. However, professional support is prevalent in R300-S’s and it’s great to see the teams in the Caterham paddock promoting our championships.
