Provided the wall thickness and OD is correct, is this legal for NHRA/IHRA @ 9.99/135? TIA

 

not with 100% certainty, but the door bars arent legal, no diag bars. i dont think it is legal. but i have seen some shady stuff fly. well not that had to be cert'd.

 

i say no, the other then what was posted above the plates arent 6x6, where its mounted to the car, and with bolt in you have to have plates on the bottom as well

 

Door bars are a definate no go IMO, shouldnt the harness bar be one piece?

 

pre fab get an s&w...or something else, just not that crap.

 

this example is more for autocross, scca type racing. this wont pass for drag NHRA spec

check out the NHRA rulebook on cage specs

dont waste your money on that crap......

 

Its good up till 200mph in a nascar race. j/k

 

Those cages probably arnt legal even for a 11.49 car.

 

I heard one of the NHRA tech's drill a kid on his autopower roll cage durring tech inspection before. "there is nothing that makes them legal for NHRA" is what the tech said. Tube diameter is too small, wall thickness is too thin, bolted together isnt a good idea ( i believe nhra requires the cage to be welded together) and the tech was also talking about the ^^^ floor plates not being 6x6".

 

D bars and door bars are definately not legal, as well as the obvious floor plates.

 

its a bolt together cage. SHOW CAR ONLY.

the only thing that can be bolted is the door bars(swing out style) & thier only good to 10.000 sec. after that welded only.

that cage probably isnt even chromemoly.

& for the record door bars must pass between your elbow & shoulder when u sit in the car anywhere else u can fail tech. & maybe cage sert if they get technical.

 

x2!

 

We have u-weld cages and bars available for EG (92-95 Civic) and DC2 94-01 Integra. We can even provide some of the bars pre-notched.

 

OP, if your that serious, buy a NHRA rulebook. Do it right and safe the first time. There's more at stake here then just your car.

 

That's expensive jungle jim for my son. LOL J/K
