Sonderwunsch can do other modifications but it is *extremely* rare and obviously super expensive. They’ve done a one off 918 Spyder with fixed rear wing and other modified bits, a customized 992 GT3, and the Classic facility also does non-cosmetic modifications for clients. It’s not often, nor anywhere near as extensive as what Ferrari does… but they do more than just cosmetics sometimes.

I would definitely do that to my 991.2 GT3 ! That's the best part of my 997.2RS compared to all the other factory 997 GT3. If it were to do it again i would get a 997.1 GT3 and just slap the 3.89 of the 3.8RS and a LWFW Single mass. ( but i got the 3.8RS instead because at the time i didn't knew i could do this ).
I am expecting this mod to be trendy in the near future and that a few 991.2 and 992 owners will do it. If it is below 20/25k all in which it should be, it is a steal and will fix the achilles heel of this car's too long box.

911R LWFW conversion on the 1.2 is not possible due to changes in the crankshaft. Low mass flywheels transmit a lot of potentially harmful vibrations to the drive train and bearings and the noise is definitely an acquired taste. It's a shame because I think it would improve the car.
Simply swapping out a flywheel isn't rocket science assuming the clutches are the same, but I suspect Porsche made accommodations to the S/T drivetrain to deal with the chatter and noise issue. Access to bespoke S/T parts could be restricted, I'd imagine.

"Yes, a dual-mass flywheel on the manual transmission. We had it on 911R as well, but you could opt for a single-mass flywheel, which most everyone did. But in the new 4.0-liter we have a different crankshaft, and it is stiffer because the main bearings are larger in diameter, which increases rotational inertia. A single-mass flywheel will fit, but we found out it hurts the main bearings. And all the people working at shops who have the great idea to fit a single-mass flywheel to the car? Don’t. It will void the warranty. But the car doesn’t need it; it revs so explosively, the 4.0-liter is such a cracker of an engine, that it doesn’t miss it."
Obviously, they changed their mind on that point.
The issues of vibration and noise are real and that's where I wonder if there is more to the S/T to accommodate it.

Time will tell, but we will need a first lab rat to do the testing of course, and see if the 992 S/T engine differs in any ways or not.
From the few videos i saw, of the engine revving, it felt that the experience would be worth the hassle. The way it revs is motorbike or GMA territory almost.

Flywheel/ clutch should be straightforward.
Part Numbers for required parts:
Part Numbers for required parts:
- 1x 9GT 105 273 (Flywheel)
- 10x PAF 906 651 (Flywheel screw)
- 1x 9GT 141 015 (Clutch kit)
- 1x 9GT 141 719 (Lever)
- 1x 9GT 141 251 (Kugelzapfen)
- 6x PAF 010 315 (Screw)
Anything that starts with 9GT seems to be S/T-specific.

Question is whether they will ask for vin # etc when ordering the part. A good start would be the single mass flywheel and the lighter clutch. Actually all I would be interested in, I like the gear ratios as they are and everything else on touring.

I am sure Suncoast etc. would source parts without a VIN
