The harness is both SFI and FIA certified. The SFI expiration is June 2022. The FIA certification is end of 2025. Is this harness rules compliant for the 2023 challenge?

FIA usually is a higher standard and should still be valid.

In reply to wvumtnbkr : Logic would lead me to agree with you. However the way the rules read it seems that they are going with the 2 year SFI limit. Hoping for some official clarification. Seems silly to have to replace a harness that has nearly 3 years of useful life by FIA standards.

Most if not all Challenge safety rules are because we run at a NHRA track.  That means SFI limit.

And the reason for 2 yrs on belts is that's the limit on fighter jets, which sit in the sun all day everyday. They refuse to budge.

But apparently no UV evil to OEM belts and webbing...

...even if they are 40 years old!

Apparently sweat, petrochemicals and rodent waste combine to make the world's best UV protection.

Yes , that thought occurred to me. Now that I have asked about it I am kind of aware that I am technically not compliant.
