I am just trying to make a conclusion from what is posted here, not sure.
It seems the chassis tag is an SFI requirement, not an NHRA requirement. But since NHRA requires an SFI chassis for faster than 8.50; it is required for those certs.

I am looking for local info on chassis inspector in NC. I have one lead (name) and a big racer is checking his contacts for me.
