Front Engine Dragsters / Re: Cage/Helmet Clearance
« on: September 21, 2022, 03:47:00 PM »Started constructing and planning the roll cage for my FED. Driver was here today and we mocked it up with him in the car, helmet on, with 2" of clearance over the top of his helmet. To that we added the thickness of SFI padding to be installed. Called S&W race cars where I bought my chassis plans and talked to a tech. He said there's no actual minimum but to have enough clearance for some head movement, and not so tight to hamper doing a quick get-out in an emergency. So, am I on the right track with 2" between the helmet and the roll bar padding? It seemed to me that too much clearance would be as bad as not enough.
I'll appreciate thoughts.

There is an actual minimum listed in the SFI spec. Either 2 or 3 inches I can't remember and it doesn't really seem to be enforced
