Mine is a 99.9% road car, I just fancy a track day after two years of ownership. I really don't want a full cage for road only use, for numerous reasons including seat access, never intend removing the windscreen and minor worries about my un-helmeted head rattling off the cage as I'm 6'2" and don't have a lowered floor (yet).
I have a friend who races MX5s who can get me a rollbar made; what spec do I need to comply with for club track days?
