Suggestion
Basically, the test procedure is to twist the pressure plate surface of the flywheel about 15mm to both the left and the right and check to see if it returns to approximately its original position.

Suggestion
The 911 Carrera uses a dual-mass flywheel, which is a two-piece component that is bonded together.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I linked a lot of Shaeffler LUK diagnostics videos some time ago. The friction plate is easy. The DMF is a frequent source of misunderstanding in measuring the rotational free-play.

If you want an opinion, then YES, replace. The flywheel surface should be perfectly flat and yours shows a wear pattern that has worn down the surface and left grooves. Would it not be worth peace of mind, since you are already there, to replace it and know you did right? I know it is expensive, but with all the effort to get there to this point, replace. When I get to the point of needing a clutch job done, it will all be replaced.

"With the pressure plate removed, you should be able to see the flywheel. The 911 Carrera uses a dual-mass flywheel, which is a two-piece component that is bonded together. This changes the natural frequency of the flywheel and reduces vibrations in the engine. Unfortunately, this flywheel can be expensive to replace. Porsche has released a Technical Service Bulletin on checking the dual-mass flywheel (TSB 911 8/02 1360), which I have placed on the 101Projects.com website for reference.
Basically, the test procedure is to twist the pressure plate surface of the flywheel about 15mm to both the left and the right and check to see if it returns to approximately its original position. If the flywheel cannot be twisted at all, or if the flywheel can be twisted beyond the 15mm without a noticeable increase in the spring force, then the flywheel is likely to be faulty. Typically it's a wise idea to replace your dual-mass flywheel every 100,000 miles or every other clutch replacement

Yours looks fine to me in terms of spring return. However, the wear seems to be a bit deep and there's a clicking noise. If you can find someone locally that does resurfacing, that may not be a bad idea. In any case, you should use a new pilot bearing for sure.
