As many tracks as I’ve gone to and as much tech I’ve never had anyone ask about my flywheel. But that one would go back to get a fresh date from who I got it from.
My big track a Brainerd Int Raceway will ask if an aftermarket flex plate is used. And if a tranny blanket. I can truthfully answer yes to those questions. Are they current to today's SFI standards?
That I have not been asked. But I bet if car does ever go under 9.90? That topic will be get closer scrutiny. Among other safety concerns. Lol.
