Tube bars out to front frame on a mopar?

Coleydog · 07-12-2016, 04:54 PM

I guess we need to know what they mean by "front braces". Is the "roll cage" just permitted in the driver compartment on 9.99 and quicker with no bars going to the front rails? Very hard to interpret how it's worded. The cars are faster now and the rules are still in the 60's it seems. Without some form of "bracing" some of these unibody cars are dangerously coming close to breaking apart within a year.

Hi,

The rule had always been..........

Nothing through the firewall......

I don't think that it would change because a cage was the car.....

A K/SA can run a cage if desired......

Just making Stock into Super Stock and Super Stock into Comp....

Guys that was amended 10/26/15 to section 10A, section 7 page 23 It is legal to run the bars thru the firewall on the inside or over the top of the inner fender .
However section 4 above it says its not , it has been legal since the start of this season. ....You know NHRA never makes mistakes in the rule book !
I double checked this with Dave Ley before I did any.

Tom, I looked at the published amendments from mid-2015 and all the publications since then and do not find what you are talking about. In fact, the 10/26/15 amendments are still on the NHRARacer.com site and I do not see that in the document there either.

Here it is

SECTION 10A: STOCK CARS, BODY:7, FIREWALL (Page 10) (10/26/2015) Alterations prohibited unless expressly permitted in this section. Firewall coverings prohibited. Where heater/air conditioning units have been removed, area must be covered with minimum .024- inch steel or .032-inch aluminum, including rear hood seal/flange, as on GM A-body. Minor firewall modifications permitted to C5 and C6 Corvettes for transmission installation. Roll cage tubing may run across top or side of inner fender well/strut tower and attach to frame horn. See General Regulations 7:4.

Ahhh! I was stopping at the Roll Bar Section; did not read the Firewall Section. I stand corrected.

Mark Yacavone · 07-13-2016, 09:39 AM

Anyone want to guess why that rule was changed, and who for?

"FIREWALL
"Alterations prohibited unless expressly permitted in this section. Firewall coverings prohibited.Where heater/air conditioning units have been removed, area must be covered with minimum .024-inch steel or .032- inch aluminum, including rear hood seal/flange, as on GM A-body. Minor firewall modifications permitted to C5 and C6 Corvettes for transmission installation. Roll cage tubing may run across top or side of inner fender well/strut tower and attach to frame horn. "

The last sentence has never been made clear (at least not to my knowledge). Does it apply to the corvettes or all stocker?

Tom Goldman · 07-14-2016, 07:46 PM

It applies to all Stockers.
