Trackday Convertible Safety Requirements

[TheArchitect]

Hi Guys,

I'm looking at buying a mk3 MX5 and will be doing the occasional trackday in it. I will be buying a crash helmet for the track day events as they're surprisingly affordable for what looks like good FIA BS approved helmets, however I imagine once I have a helmet on my head will be higher than the line between the roll over protection (standard) and the top of the windscreen. is this likely to be an issue with the track day organisers? as I don't want to turn up and be turned away. I understand most vary but I want to allow for the strictest that way I know I'm covered.

I've never seen anyone turned away for anything like that, they often specify full face helmets in open top cars but it isn't often enforced.
