I don't understand why a "qualified Porsche technician" would even make a post like this in the first place.

Stirring the pot, perhaps?

Doubtful the poster has any mechanical skills and is just asking a question.

Why try to repair something that isnt broke, I would fix leak and send it down the road, not "ALL" bearings are failing, the upgrade kit is still "NEW" and who knows how long they will last?? If you are planining on keeping car for a long time, then maybe worth the security and investment, but to resell for a profit or flip this car, I wouldnt touch it.
