Cage and harness question
Can anyone tell me at what point (below what et./above what mph?)you are required to run more than a 4point roll cage on an NHRA (Maple Grove) sanctioned track?
Also along the same lines, at what point must you run a racing harness instead of a factory seat belt?
Thank you!

I can't answer your questions (been a long-time since I read-through an NHRA Rule Book, but I believe you'll need a harness at either 11.99 or 11.49 ), but some of the guys on this Forum who build chassis may offer help:
Forum-member CFI-EFI is very knowledgeable about safety regs, and since 'da Grove is so-close to Division One HQ, I'd follow current NHRA rules to-the-letter.....
Your best-bet may be to contact Maple Grove directly, in-case any of their Track Rules superceed the current NHRA policy.

9.99 requires a full "cage", slower a "roll bar" will do.
9.99 also requires many other safety items, multi layer jacket & pants, trans sheild, SFI flexplate, ....... best to get a rule book and talk to your local tracks tech inspector.
Good luck,
Dave

It is 11.49 you will need a 5 or 6 pt bar, a 5 or six point harness and an fire jacket (single layer)
Here is the NHRA quick reference guide for safety

The rule-book only mentions roll-bar or roll-cage. When talk about roll-bar, it's a 5 or 6-point and a roll-cage "must be designed in an attempt to protect the driver from any angle, 360 degrees."
For et's between 11.49 and 10.00 a roll bar is required. But, if you're running between 10.99 and 10.00 and faster than 135mph you must have a roll cage. And also if you are runnig 9.99 or quicker.
Qoute: "A quick release, 3-inch shoulder harness meeting SFI Spec 16.1 is mandatory in all cars in competition required by the rules to have a roll bar or a roll cage."

Thanks a lot for all the info!
I have a six-point right now so I should be fine. I dont expect the car to run any faster than 11.5, so I exempt from the halo bar and saftey clothing
I will follow up with the techs at Maple Grove.
Thanks again guys!

I would talk to Carl on this one.1-858-451-8868
The problem is all tracks though they are NHRA,decide on what they want to call .
The vett usually falls under the convertable rule.I would count on 10.99
you need everything,the pop top or "T" top in the vett can be decided in eather direction.It might be a convertable or not depending on the track.
I consider the t top as a 11.49 car.
I installed an 8 point bar and was done with it.
I am a tech inspector and one of the motor cycle guy's is an inspector
and was giving me a hard time ,you cant inspect your own car.I fixed him ,I asked where is your wrist kill for the bike?
He said I don't need one .Wrong I threw the book at him and ended his night of racing .
Later we aproved each other vhls and nothing more has been said since.

I have raced at a variety of NHRA tracks. For years I have raced at the NHRA conducted, and tech inspected, NHRA Division Finals.
I have never seen a Corvette coupe treated as a convertible. I HAVE seen convertibles, with removable hardtops treated as coups, however.

having-said-that, in 26+ seasons of 'hanging-around' various drag-strips, I have NEVER seen T-top coupes (C3s, 2nd & 3rd generation F-bodies, etc. ) be classified as 'convertibles' by any NHRA Technical Staff, and agree that hard-top convertibles are classified as 'coupes' in the eyes of NHRA and IHRA.
