Thanks for the tip - because I would not have considered it.
Hmm...flywheel bolts are much closer to the centrum and thus subjected to much higher shear force due to lever principle. They are also 12.9 grade.

Of corse, it's better to be safe than sorry but if Porsche put 8.8 grade bolts there, it cannot be so critical.
Thank you for your time,
