As an NHRA tech for Division 3, I can confirm, there has been a rule change for 2012, and the ribbon style nets ARE required to have SFI date tags and and are good for 2-years just like the seat belts. I don't fully agree with it, but that is now the rule.

I personalty talked with one of the head guys for SFI and he indicated they have found when testing belts and window nets that even if kept out of the sun and in good condition, they lose some of their strength just from aging.



We had a guy on here a few years back that tested
belts.... some nasty lookin ones... in each case that
he tested... the latch gave way first.... he never
once had the webbing give out.... and in the testing
I watched at work it was the same way... that webbing
or seat belt material is STRONG stuff(and that was
2" webbing)and we are required 3" except for the
crotch belt which can be 2"..... I dont see the need
to change out a web style window net every 2 years...
the purpose is to keep your arms inside the car(and
the net is suppose to be mounted in board so it cant
be ground away if the car is on its side... its
not a strength issue........JMO





You so called tech guys, all you have to do is show us the results of the tests showing us that belts fail. Just show us the tests and we will shut up.

That is all I'm asking for before I throw another $100 in the trash or just quit.

If the belts and nets really do fail after two years, how come the HANS device straps are good for five years
