Anyone here ever done a Curborough Sprint day (UK venue)

If so, is a helmet absolutely required? I can't fit in my car with a helmet unless I could somehow lower the seat/remove a vertebre/angle the seat too far back.

The venue is being hired out privately for the day if that makes a difference.

Why don't you just call or e-mail them?

You probrably will, any 'speed' event usually requires a helmet.

MSA speed events require MSA approved helmets and overalls, they must also be in date. Unfortunately this is a considerable expense. If you're not running a close to standard car you'll require a rollcage and all the other safety bits.

Track days usually accept anything that looks vaguely full face, out of date racing helmets are ideal (but only use them if they fit and you know they've never been in an accident) or you can get away with some motorcycle helmets (cheap but not great).

If you can't fit you're head in your car with a helmet on I'd look at moving the seating position, presumably you're head is at a high risk of hitting the car especially if you haven't got harnesses.

cut a hole in yr roof! sssshees.. do i have to tell everyone what is best thing to do... :jawdrop:

Depends on the event organiser usually. A lot of events at Curborough don't require helmets.
