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.

(As it states: --- In ALL other categories ---- )

Below is directly from NHRA:

************************************************** ***********************

In all other categories, effective January 1, 2020:

(a) any rear wheels originally certified as meeting SFI Spec 15.1 must bear a wheel conformance label indicating compliance with SFI Specification 15.1 properly affixed to each wheel per the specification;

(b) any rear wheels originally certified as meeting SFI Spec 15.3 must bear a wheel conformance label indicating compliance with SFI Specification 15.3 properly affixed to each wheel per the specification (including re-certification if applicable); and

(c) any rear wheels originally certified as meeting SFI Spec 15.4 must bear a wheel conformance label indicating compliance with SFI Specification 15.4 properly affixed to each wheel per the specification (including re-certification if applicable).

************************************************** **********************

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.
It says -- ALL OTHER CATEGORIES --.
