Thanks for the info. I know SCCA and NASA will let open-top cars run; in the 4 track days I did with NASA, the Miata was the most popular car.

Thanks again.

I think you will find for profit companies generally allow convertibles, some with no more than the factory hoops.
Some BMW chapters will allow convertibles with approved rollbars and safety equipment. They generally require a logbook from a known sanctioning body.
This is important because there is no way someone teching cars would know if it was properly installed. I recall seeing a rollbar that wasn't even secured to the chassis making it extremely dangerous in any incident Our insurance rates are also based on following minimum standards.

Personally I feel open top cars are at a greater risk when gravel traps are near track out.
