I am not a member (yet). I click download pdf and it downloads on my computer

That's what I was referring to. Roll cage to tie together and prevent frame twist, then anti roll bar to prevent suspension twist. Obviously solid bushings to help stop suspension movement (and body bushings too, as you stated). I also prefer adjustable shocks for fine tuning. Some of this is referring to coil spring cars in general, (my Mustangs), while some of it is from previous A bodies, I have owned. (Monte Carlo, several Chevelles). These are my choices, others may have a different opinion.

So, if you won't spend the money to to join the NHRA to learn how to build a Stocker then why are we having this conversation?

Re: Ol' Fart's Firebird Fantasy
 

I wondered this myself, lol. And although I have not yet joined either, I am in the early stages of my build, and will as it progresses. The link I showed downloaded the 2014 rulebook, which in these early stages is all I needed.

Re: Ol' Fart's Firebird Fantasy
 

Yeah, if I understand the general rules I looked at online, it appears that all cars must have at least a 5-point roll bar which includes a driver side bar. So, I assume that a good 6-point will strengthen the body / frame enuff for 11 or 12 sec Stocker duty. :)

Found this info in section 20, page 20-21 under "4:10 Roll Bar" There is an illustration on page 21.

Re: Ol' Fart's Firebird Fantasy
 

You should reread. All cars are not required to have a rollbar. It is ET specific.

Re: Ol' Fart's Firebird Fantasy
 

It is CLASS specific. N/S and lower do not need a rollbar.

Re: Ol' Fart's Firebird Fantasy
 

OK, I reckin I can't read. I just read thru it again. It says that all cars with frames must have the roll bars bolted or welded to the frame, and all unibodies must use plates welded or bolted to body, etc. Also tells and shows how to attach seat to roll bar.

So, are you saying that some cars can use a stock seat even without a head rest, and no roll bars, if they go slow enuff ? I'm sorry to ask such infintile questions. But if I knew the answers I wouldn't be asking. :o

Re: Ol' Fart's Firebird Fantasy
 

I guess we are both right. Let an N/Stocker run quicker than 11.49 and it too will be getting a rollbar,(and a HP Factor), LOL. But you are correct, as it stands, CLASS specific in Stock.

Re: Ol' Fart's Firebird Fantasy
 

Billy , is exactly right about N/S - N/SA & Higher ( O,P, etc. ) That's another advantage for your build ...
