We don't have anything to worry about in Stock and Super Stock.

So happy to see this. I was sitting here thinking if I try to race next year, I would have to buy new wheels too. Thank you!!

For S/SS, this can of worms is better left unopened.

I just watched the factory stock finals on tv at charlotte. Drew skillmans mustang as it crossed the finish line looked like it had the biggest 9 in tire or widest rim on a 9 in tire I've ever seen. Is this the way they get them to stay hooked up?

CLASS, MPH, or ET does NOT matter.

Below is directly from NHRA:

If your wheels had SFI stickers on them when NEW they better have them on come January 1st.

Don't want anyone getting bounced because they thought the rule didn't apply to them.
