Stock Eliminator suspension
 
Looking at the NHRA rule book it states "aftermarket tie rods with Heim joints permitted"
Does that include the front suspension strut/tie rods?

No.
One of the few things NOT allowed in S/E.

Better double check that Mark, I thought it was allowed when NHRA also allowed the stock Elim roll bar to go thru the dash and into engine compartment .. Disclaimer …. My memory is not what it used to be. :)

SUSPENSION, FRONT
Must retain complete stock front suspension system as
produced by manufacturer for body used, aftermarket tie rods
with Heim joints permitted. Lower control arm may be machined
for larger shock diameter and mount. Lift kits/travel limiters
prohibited. Sway bar optional. See General Regulations 3:4.

Well, it DOES make it easier to fix "bump-steer".

If I heard right, one long time stock racer I talked with said the QA1 strut bar was allowed now on his car (Demon).? Back to square one if not allowed.

You are good.

I stand corrected then.
I know, when I was helping out a bit on the Tbolt, about 6-7 years ago, they weren't allowed. That was source of movement that was not good.
Some of you might have noticed a bracket car or two with bad bushings. Seeing the front wheels move back and forth while staging was a REAL safety issue.

Mark,

You are correct!
It took NHRA some time to understand it was a safety issue, especially after a wheelstand.

As I understand, it was Troy Olsonawski who brought up the issue with NHRA and the actual risk.

Re: Stock Eliminator suspension
 
Great news, with mine now there is no movement front and back when wheels are in air back to normal height. A lot of time went into fixing that and the bump steer.

Re: Stock Eliminator suspension
 
I reached out to NHRA and got this response??? Definitely more confused than ever.





" Are you asking if the strut rod can have spherical rod ends; if so the answer is no for Stock Eliminator, They are permitted in Super Stock."

Thank you for the correction!

As usual, no common sense!
This is a safety issue and it does not apply to Stock Eliminator?

Aw c mon NHRA get your act together. Nothing is ‘stock’ about stock anymore.

I wouldn't worry too much, just yet. NHRA might change the rule by the time you get your car done.

I thought the string here was about stock. I went back to the NHRA site and found this note in Superstock. In the stock category, there is no allowance for the strut rods with heim joints.
Maybe I missed it ?

See posting #13.

Ok thanks. I agree. There are some inconsistencies in the book for sure.
