It is an artifact from the injection molding process. This unintentional feature is commonly called “sinking” and occurs at thicker locations on the part’s geometry. Ideally, injection molded parts will have a uniform sickness across the entire part… But discs have a thicker section at the rim. This thicker section is where the sinking occurs. This artifact is caused by unequal cooling times due to the wall thickness variation.

Yup, I’m a nerd.

I’m amazed Innova hasn’t added a letter designator like C or something to the runs where it’s more pronounced. And call it a feature instead of a flaw they just ignore.

Maybe it’s just that I don’t handle too many different molds but it seems some are more susceptible than others. Like it may have to do with the spacer?

You just saved me from having to type pretty much exactly that!

That works if you think Innova cares about quality or defects. They clearly don't.

That’s kinda my point.
Oh damn these rims flare out way way past vertical. Oh that’s ok we will call it a “plus” rim and sell it as a good thing.

Hey look someone effed up and put a leopard bottom on this run... oh we will call it an L version people will love it.

Wow our molds are getting old and all our discs are coming out overly domey we should fix that.
Nah we will make some new ones but keep using the old and the new we will call “3” molds and change the flight numbers that way people will buy both.

This is normal. I don't think you have a case for replacement as your disc looks perfectly fine
