Roll bar questions?????

[goinbroke2]

Make an imaginary line from the top of the bar forward to the top of the hood. (in case the front a pillars collapse in a rollover) if she is low enough to clear that, I wouldn't worry about it. I rolled my mustang when it didn't have a roll bar (on the street) and the back half of the roof stayed up and only the a pillars collapsed. The front of the roof came down until the car was resting on the hood. It would be the same with a car with a hoop, the roof would cave in until the hood hit.

I'm just thinking down the road when either she's taller or someone else is driving and there's all these extra bars in the way and have to be removed again.

Have spoken with tech today and I was informed they would be more concerned with head support than the hoops locality to the helmet, I'll also get a second opinion from a different tech person. So far all my questions to NHRA officials have been met with great courtesy. Thanks for everyones responses and help.

Would love to have your problem Todd...my helmet is against the hoop every pass in the cramped/confined El Camino.

I am tall from the waist up. With the stock seats my helmet was against the roof. When I put the racing seats in I bolted the seat directly to the floor and that fixed the problem with head clearance. Gen 1 Camaro.

Go to Section 20 page 27 in the NHRA rulebook and build the rest of the rollcage. Problem solved.

I thought this was going to be a team driving effort, I'm now seeing that any car she drives will be near impossible for me to drive. May have to buy another car.

See how expensive kids are to raise? Now you need another race car! LOL!

Not to butt in on your thread but I was reading Section 20 page 28 and saw this . " Aftermarket aluminum seats must have reinforced head rest. " I never been hit with this but I thought is mine?

The reason the rule book states "Aftermarket aluminum seats must have reinforced head rest" came from the first time we saw them in tech years ago. The original high back aluminum seats were weak in the head rest area and could be easily bent back. The new rule was soon written and the manufacturers redesigned the upper portion of their aluminum seats.
