Super stock GT question
 

I was just wondering if I could use aftermarket tubular a-arms and k member on a 1999 firebird in super stock GT. Thanks, any help is appreciated.

I know in IHRA you can't. I was accused of cheating last year with one, went through tech with all my stock junk an was fine. Still a little upset on how everything was handled. I don't understand why you can 4-link a car but you can't run a tublar front suspension. It keeps it in the factory location....makes zero sense.

This subject has been brought up many times on this site.

Also, I have addressed the subject with NHRA a few times including some RWD cars that have been built stretching the rules.

In a nutshell, OEM K-members on late model cars where not designed to handle the loads of wheel stands and high torque engines. Nevertheless, cannot understand why FWD and given so much leniency when compared to their RWD counterparts, expecially in SS Modified classes.

As usual, requests and letters were ignored, not even an explanation of why it is not considered

what I don't understand is I've seen pictures of 2-3 stockers and super stockers that have tubular front suspension.

How do these cobalts and cars of that nature able to run one, but I can't??? I mean there back halted/4-linked on a 13in tire, yet I can't run my tubular stuff on a stock suspension on a 9in tire??

So you want to run an aftermarket tubular K-Frame that may knock off 75#'s from the front of your car? :rolleyes:

Re: Super stock GT question
 

It does not knock off 75lbs. Most of the late model RWD cars have a stamped sheet metal K-member made of a light gage thickness.

The rules allows you to modify the OEM k-member, however, in some makes of cars, it is not possible and may weaken the k-member.
I am addressing GT and modified classes and allowances given to FWD conversions when compared to RWD cars in the same class.

The FWD conversion cars have no choice but to run 4-links and custom K-members. As to why they don't allow it on the RWD cars in Stock I can understand as it by definition Stock and there aren't FWD conversion cars. The only thing you see in stock is 4-links on IRS conversion cars because again they have to if they are wanting to run a Live rear axle. In SS/GT it was hard for me to grasp how the FWD could and why not allow the RWD to do the same as they can also run 4links also. Just to even the playing field. A tubular K-member is certainly an advantage on most models.

But rules are rules. Just have to do the best you can with the cards you are dealt. You could request the rules be examined if you feel strong enough. The FWD conversion car builders certainly put in a lot of time and effort so its not really a shortcut to a fast car.

It doesn't knock of 75lbs off the front of your car. Been there and done it. What's the difference in me doing this and you gutting your car? Your logic makes zero since...

Re: Super stock GT question
 

I would agree that it does not seem right that the FWD conversions can have better, safer, easier to work on front suspensions when the guys with the older RWD cars have to battle steering boxes, tie rods through the pans, weak upper control arms and other issues. Those "little pro stockers" are going to be faster in the end anyway so why not throw us a bone.
