C400 racing

[Redmax]

Apart from the Magnificent 7s series, where could I race a 2007 C400? Would it be eligible for the current Superlight R400 series?

The one I'm looking at has the 220bhp Cosworth engine but it doesn't specify whether it has the sequential gearbox - should it have one?

Cheers

It sounds like this one may be a bit of a dead-end if I want to do Caterham-sanctioned racing. Are there other race series it would be eligible for?
