This ruling only applies to S/SS cars and I'm not saying that in most cases it isn't a good idea BUT it doesn't apply to a low 10 second bracket car so why should it apply to a "U/SA 273 Mopar" or a P/SA 301 Pontiac that rarely if ever sees over 6 grand?
And where am I supposed to find this 301 Pontiac SFI approved flex plate?
Maybe a re-think and a change to 11.99 or quicker might be prudent?

Seems to me they rush out these new rules to head off a lawsuit,rather than thinking them through first.
Then again, maybe there's no one out there that CAN think them through first

Billy maybe they're afraid of scaring away kids with newer high powered street cars that come to run bracket.

Maybe a call to our division tech rep, whoever that is right now, or somewhere higher up the ladder will get an answer. i can't really believe if they don't make one, that the answer will be that you need to park the car.

Option will probably be some kind of flywheel shield.

So..is there an expiration date?
I have an SFI flexplate on my car now that I will examine for any cracks etc..but does it make sense to take one off that has never broke,and replace with one that might?

Does each and every SFI certified product have to go through the required testing to meet the standards. Asking if someone in the know can answer, thanks.

[Steve Grady]

A representative sample of the actual product is tested. Product is then considered SFI compliant for that part number. Any changes requires retesting.

Just internally balance the rotating assembly then no need to modify the SFI flexplate. Hopefully everyone sees me being a smart *** about this.
