Replacing "expired" harness belts?

[RSO 34]

I have a set of Schroth 5 point harness belts that I have used for 5 seasons. They have a total of 50 track days of usage over those 5 years. The label on the belts indicates they should be replaced after 5 years (the belts are actually 7 years old but were in the box for about two years).

With that type of track usage solely in HPDE, do I actually need to replace the belts or can I still use them safely?

I would replace Bob.It has alot to do with gradual breakdown of the material due to uv exposure.They may look good but could fail in "the big" one.
