This is a "gray" area and I know what I want to do, do I need an approval or just build it?

Thanks Bill

Have fought this with NHRA for the past 3 years to no avail and my last proposal, was also shut down. In a nutshell, any OEM RWD car must keep the original, as delivered, suspension system, including control arms and front shock configuration. You can only modify the OEM cross member as shown and described in the regular RWD Super Stock car rules.

There are a lot of aftermarket suspension systems with fabricated cross members and lower control arms; however, they are not allowed even if you send a request for approval. They will not even allow an aftermarket cross member with the OEM upper/lower control arms.

However, if you build a FWD, that is a different story and they allow fabricated components in accordance to the rules.

Just check out some of the FWD cars with 25.3 and 25.5 SFI chassis and you will notice they are the closest thing to a Comp car.
