[QUOTENow Nader's, on the other hand, I think is way too tall and would be given to structural failure in a rollover. You should have an engineer, someone good with structural dynamics, take a look at that.
Actually Nader`s roll hoop is way outside technical specifications, and is very unsafe.
Far too tall relative to the support members.
Rather than moan defensively because it is not only ugly, but unsafe, he should invest in either a SCCA GCR or purchase the chassis design specifications manuals from SFI (SEMA Foundation Inc.) used by most organizers inc NHRA, IHRA, SCTC, (Bonneville) etc.
He won`t be happy to be excluded at an organizers event that actually "scrutinizes" the chassis build.
And, to prevent future debate all 3 of my cars, the Duetto, GTR, and the Montreal "Coupe" have inspector stamps from a SEMA inspector on the cages. (SEMA / 55) Foy Gilmore (go ahead Google him!)
For the less aware, don`t forget the distance below the roll hoop for the helmet top is 2 inches. And that is from the TOP of the hoop. I have about 3" when not farting.
