BTW, Kudos to FVD for such an obvious and clear "Note":
Please Note:Installing a lightweight flywheel can cause light gear chatter. If you are ok with a louder exhaust, greater intake noise or more mechanical sounds, then this should not bother you. If you must chase down every rattle or squeak, then this may not be the right modification for you.
After listening to an engineer speak on this subject, I would not install a LWF in a 991 or 992 that didn't come with one (i.e. 991R). The gist: "You'll absolutely love it when you drive away from the shop, but you won't love the second bill a little later."
The good news is I don't find the 3.0 7MT bad at all.
When I start thinking, as tonight about headers for my 991.2 S, it brings me back to the fact that Porsche has an army of engineers that seem to know what they're doing and put out a product that we all like, a lot.
Sometimes it takes an effort not to meddle with things, seems a lightweight flywheel is one of them, another is replacing my PSE.
Save your mod money for driving schools like I did.

Well there are ALWAYS compromises for the masses, most folks on the forums don't fall under the bell curve and are willing to take a louder, rougher riding car etc for performance and visceral feel. The engineers DID NOT engineer our cars for maximum performance, but built in durability, and general NVH for their main target demographic. To your point I also invest in driving instruction and track days A more responsive motor sounds like fun, these are toys after all.
I would advise strongly against this for street use . I put an RS flywheel on my 964 and it ruined the driveability of the car. It was a lot faster but the juice was not worth the squeeze.
Now 35HP for headers and a tune at 3K, thats is a pretty easy choice and a yes as it is not changing their engineering it is merely making the car faster by skirting the EPA regulations Porsche had to follow as a manufacturer. Living in the Flor-i-duh we have no state inspections to worry about and really if a car has 4 wheels it is considered safe here. On a side note, in Florida good insurance is key.
991.2's have an integrated dual mass flywheel with a centrifugal pendulum for both PDK and manual. 991.2's also moved to a double plate clutch. Integration of the Turbo gear set and ring gear/pinion shaft with shorter constant ratio in 991 PDK and Carbon synchronizers adopted from 991 Turbo.
Seems to be a bit of a different animal then the 991.1. From what I can tell 991.1 Carrera cars were closer in kin to the 997.2 Carrera cars where the 991.2 adopted more stuff from the Turbo family (by model designation) when it comes to driveline durability. Fine by me given how well its held up for the Turbo folks and they are dealing with 100-150 additional ponies and torque.

Makes sense as turbo motors delivery power differently than N/A so it makes sense they adopted the technology from the REAL Turbo models.

Don't think that Porsche designs and engineers their cars for the masses. We are the relatively small number of lucky ones with the ability to indulge.
Do think they have a balance of reliability, longevity and performance in mind when they work through their design and manufacture. As well as making a tidy profit, that is a given.
However, you have personal choice, spend on what makes you happy.

What I meant as "masses", masses within the market for folks that buy 911's not the globally LOL. My guess is the target demographic for new 911's under the bell curve are older (45-55 year olds) who like to have a "Sporty car", but with the refinement (quiet, drivability) of bordering luxury car. Hence the 991 has become more of a Grand Touring car than the pure sports.
But to say they optimize for 100% pure performance on really any cars but perhaps the GT level trims and cup cars, no way. I bet if you rode in my car you would HATE it with the monoballs in my suspension, metal shift cables and full exhaust and headers. I just wanted to see if anyone her ACTUALLY installed a lightweight flywheel versus experiences from other cars or "theories" that Porsche engineers maximized performance.
Feels to me like it was designed for the masses and is the first miss in 911 history. The interior is completely busy with 3 of everything in the wrong place with a quirky mix of ***** toggles and buttons. It reminds me of a girl wearing too much makeup, sad. There is no drama only speed. I preferred the driving experience of the Taycan, it felt more "true".

Curious to hear more on this topic as well
