Thanks David,
But that rule is very vege, meaning that that they could disqualify the car in tech inspection, depending on who is inspecting the car. I know that they are not required in some classes, but i still think they should meet SFI if they are reguired, and not advertised, as NHRA approved.
I also have the 2008 rule book, since i'm a lic. NHRA driver.
