I got scolded going threw tech saying that I needed bolt on valve stems in my wheels. I never knew this rule and have been racing the car for a few years and know one ever said anything and even got my Nhra license a few weeks ago. Was this a rule change or something? Anyway the guy said he will fail me next time if I do not have them. So my question what one do I get for a weld rts wheel. I called weld and the guy said standard but that made no sense as I see there are different sizes.
