not read it all but have looked at the "blue book" before when went to a sprint course open day

the "blue book should give you all the info you need for sprints etc

it appears to be available free online

I would assume you would be in "Modified Limited Production Cars and Modified Specialist Production"

I've been to a few sprint days and reckon your car would be awsome

AFAIK they have competative sprint days at Llandow
