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.

He mentioned this when the SP48 Unica debuted; he didn’t necessarily imply that that particular car was high seven figures.

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.

I installed a LWFW in my 993. Cost was effectively nothing over the cost of a routine clutch replacement. Of course that's an off the shelf part. The difference was transformative. The car is not actually faster, but heel toe is much easier and it feels faster.

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.

I’m pretty sure the crankshaft on the 992 is same as 991.2, so it must be possible if the ST has a SMFW (or is it just a light dual mass unit?)

I recall AP stating somewhere that smfw could not be done on the 991.2 without risking damage...

Re: SWFW on the 1.2...

"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.

Classic AP changing his speech in between each generation... i don't believe what ever he says anymore.
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.

catdog2

or F430 manual territory... lol

Parts diagrams below (not accurate because they don't show the S/T-specific parts, but just to get an idea that it won't be rocket science to retrofit... Anything's doable if you're brave enough and this really doesn't look bad.

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.

cactusjack

if ordering at the dealer, then maybe they'd want a VIN or proof of ownership.

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

This would be epic, someone needs to do this
