Roll Cages vs. Roll Bars in higher class cars - Page 2

Larry Curtis · 10-05-2011, 11:51 AM

The only downside to runnig a cage is that it has to be certified every 3 years. A roll cage that is not NHRA certified is only good to 11.50 et, a roll bar with a un-modified floor pan is good to 10.00 et. I would still put a roll cage in. $0.02

My understanding is that the Cage only has to be certified if the car
is fast enough to REQUIRE it to have a cage.

My car has had Cage and been race continually for 18 years and show
No Flex of Body unlike a lot of my other cars. I believe that it further makes
the car stiffer and easier to tune chassis. We did remove Windshield to
Fab it and get everything to fit as close as possible.

Thanks Jeff, I thought you might be able to do it that way but wasn't 100% sure.

I also think this is incorrect..... No cert. required on a cage until a 9.99 et is attained...
I run a cage, no cert. @ 10.31 et....

There is a track in WI that states that this is a rule, but I just looked it up and the rule specifically states that you only need a cert if you are running 7.50-9.99. Sorry for the misleading information.

also, contradictory to what was posted below and another post a couple months ago on this board, that overly bashed a chassis builder for not fully welding the cage on the halo attachment points. the cage does not have to be fully welded. as long as the cage is properly fit and welded properly 3/4's around the tube and corner gussets are added then it will pass tech with flying colors! gussets can be in the form of small corner plates or small diameter round tube. this is how chassis builders are able to tuck the cages up to the headliner real tight on cars without cutting holes in the floor! those silly little gusset plate or small diameter roll bar tubing welded in the corners aren't just there for looks.

don't let the flashy paint fool you!

Do you have to run a window net in a stocker that is not required to have a cage but does?
