I'm posting in FI because it seems to have the most knowledgeable people...oh yeah and it's because my car is Fi'd I need a Roll bar

I've been trying to find a place that sells NHRA Legal Roll Bars for the Z without luck. The only places I found that make Z Roll Bars follow different regulations if any most of them are simply for show.
Since with the planned new mods I should hit below 11.5 within the next 6 months I will need a Roll Bar.

Anyone know of a company that sells NHRA Legal Roll Bars or maybe a decent fabricator that doesn't charge an arm and a leg.

 

We have a NHRA 6-Point Roll Bar for the 350Z, but it is still in the final testing stage (for best fittment). The prototype (may require slight modificaiton) is avail. now and the final version should be avail. within the next two months on our website.

Hope this helps,

 

Now that is some good news. I won't need it for another 2 to 3 months so the timing is pretty good.

Can you share the price with me yet?

 

We haven't set a price yet, but we expect to be less than $800.

 

Mike, you know to keep me in mind for this.... Looking forward to it...

 

Very cool, I no longer have to search. Please keep me posted on when it's done and available

 

If I recall correctly from my 1/4mile days, there are no NHRA legal roll bars at all. You have to step up to a roll cage. (the difference being you need side bar protection that runs along the drivers door). I believe these are required when you run 11.99 and faster.

 

not correct.

you need a 5 point roll bar 11.49 and faster (one point goes along the drivers door.

Roll Cages are required 10.99 or faster (or 135 mph and faster)

the rules were changed in 2005 from 11.99 to 11.49 so you're not all wrong.
The 2006 NHRA Rule Book has explicit diagrams for a roll bar

 

MrTomCat,

Is there an electronic form of the 2006 NHRA rulebook. I could use some advice on what I should be looking for with my roadster. I know the rules are different and require roll bars/cages earlier then you guys with coupes. I am also curious if a bolt-in or removable bar/cage would be allowed.

Thanks.

 

I have not found an electronic version but I can look up a few things for you.

Convertibles need Roll Bars at 13.49 (used to be 13.99)

bolt in cages/bars are allowed

 

Hum, I guess that means I need to go for a bar/cage sooner then I thought.
My last run was 13.41@109.4mph and all they told me was I needed a helmet next time I came to the track.. I am sure I could be in the low 13's if I could get better at launching... Dumping the clutch is easy but not very effective

So my next question would be when do I need a cage and would that be a 4 point or 5 point? I do not want to put in a roll bar and then in 3 months find out I need a cage with the new engine. I am expecting around 600+whp and a drop into the 11's or 12's.

Are there any diagrams as to the minimum standards I should be looking for? I know there are many ways to build them, but I am trying for something as unobtrusive as possible since it is a convertible and a show car.

Thanks,

Check with Kirk Racing, they have a Roll Cage option, just don't know if it is NHRA approved.

Also check with autopower as they also have a roll cage for the 350Z.

I am not sure your height, but I know others have had problems fitting in the car after the roll bar/cage was installed. They solved it by bolting a race seat directly to the floor.

Let me know what you go with, since I am looking too.

 

Thanks for the links and all.

I am not that tall (say 5'11") and have already put in my Cobra Racing seats..

The problem with the standard roll bars is the X brace and rearward braces. I have a convertible, and that is not possible as far as I can tell.

I guess I will have to give Piper a call and see what they think.

None of these are NHRA legal, I checked with them already

 

I'll scan in the page from the Rule Book that describes the needed setup. There's a drawing of it as well. I won't have access to a scanner till either tonight or tomorrow eve though.

 

Thanks I appreciate that.

 

This is what I got off of INfineon RAceway and they typically follow NHRA rules since they have NHRA races there.

Wow, thanks that is educational... I think I need to have a word or two with my shop to make sure my clutch, flywheel and axle are appropriately SFI rated along with making sure I have a driveline loop..? Not even sure what that is, but assume it prevents the shaft from catapulting the car if it breaks/falls down..

Thanks again,

Did you call them? There stock roll cage may not, but they may be able to modify it so it is. Or, they may point you in the right direction.

 

I am looking at getting a set of Cobra Racing seat - which ones did you buy? Do you like them?
I was looking at the Susuka GT or the Imola GT. The technology line is suppose to be the stiffest seat on the market today, yet with a big price tag.

Any feed back on your choice would be helpful.
Thanks
