Really not that big of a deal.
I always build my Cage right so it will
certify anyway. If you have to scrap the bar/cage and
build another new one = Then that IS a big deal!
NHRA License is not big hurdle.
A couple more SFI items not a real fortune and really
not a bad Idea anyway.
It is frustrating to not be able to work on your car to go
faster and know your up against a wall of restriction to going
faster!
