I have a 2012 57 JCW. I have run 2 1/2 track days. The 1/2 day was at ORP where I got the meatball flag during my third run. I was told that the roll bar was not legal. I know that in the event of a roll over the roll bar pops up to protect my head. I was told by one dealer that the front windshield is also a roll bar. I know about the broomstick rule but I need to know how many inches the roll bar (rear) extends. I'm 5'7" and would like to be able to drive in more track events. I've called MINI USA, they don't know. I've spoken with several dealers, they don't know either. Anyone been upside down or have the information I need? Thanks for any help you all might have.
