I doubt this has much to do with it 24Cr... If anything, the RS wheels are offset further outward yet same size as non RS, particularly in the rear so by my non engineer thinking, they should place even greater leverage on the attachment point...
Maybe RS owners follow instructions better?

Now consider the fact that the offset of the non-RS car's rear wheels is 63mm, while the RS car's rear wheel offset is only 48mm. 15mm of additional leverage is not a lot, but maybe that's just enough to explain the difference. It's possible that I am not accurately representing the offsets, or maybe they are actually negative offset which would make the RS the one with more leverage.
Again, I would appreciate anyone else with some technical chops to chime in and explain in more detail.

What I've noticed is on a regular Carrera S for example you can put on a 14mm spacer on the rear and the wheel will be offset right out the the edge of the fender. On a GT3 (same narrow body tub) an offset of 15mm outward will put the same width wheel out past the fender. A RS wheel will not work on a GT3 on the rear.

Are you sure about that? I agree that the RS is a wide-body, which the non-RS is not, and the wheels have a different offset as a result. But take a look at this explanation of wheel offset:

I think until you gain access to every instance of failure (which is not possible unless you have a mole at Porsche), you have no idea what your dataset really looks like. And therefore this is all just mental masturbation.
I am totally friendly towards the idea of rear wheels (of any CL car) being far more likely to fail simply due to the much greater loads imposed. But other than that, this speculation is not productive. No offense to anyone and all said unemotionally.

I also think there's utility in documenting the inherent faults of these cars. Like the RMS and coolant pipe issues, these are totally relevant concerns that should've been addressed by Porsche in the first place. PAG should know better than "playing deaf" to problems of this magnitude. If they won't do the right thing, our only recourse is to start protecting ourselves.
The more we document these issues, the more we empower individual owners come that moment of confrontation, whether on commercial or legal grounds.
