America's First Single-Marque Caterham Race Series
C7 Cup introduces the USA's first dedicated race class ladder for the Caterham Seven — one of the most unique, capable, and fun race cars ever built. Equal machinery. Relentless wheel-to-wheel racing. The fastest driver takes the flag.
America's First Caterham Spec Series
The Caterham Seven is mechanically simple, widely available, and easy to maintain. A straightforward eligibility process and a well-established parts ecosystem means more time focused on racing — and less time in the garage chasing exotic components.
01The CC4 class runs a spec Bridgestone Potenza RE71-RZ tire and a nominally 210HP formula — meaning the only variable is the driver. Every race weekend delivers door-to-door battles from flag to flag. Expect to fight for every tenth, every corner, every position.
02The Caterham Seven is a driver's car in the truest sense — lightweight, responsive, and brutally honest. There's nowhere to hide. C7 Cup rewards commitment, racecraft, and feel over technology and team resources. The fastest driver wins. Every time.
03The CC4 Class · ICSCC Sanctioned
The first C7 Cup race class — CC4 — has been racing in the Pacific Northwest since 2022, under sanctioning of the International Conference of Sports Car Clubs (ICSCC). Built on a permissive formula centered around a nominally 210HP Caterham Seven and a spec Bridgestone Potenza RE71-RZ tire.
The Caterham Seven 420R is the CC4 centerpoint car — available new from your USA Caterham Cars dealer, or convert an existing 420R to CC4 spec provided it complies with the class rules.
