Full about heel performed and gone for the 964 rs version.
Have been advised by Michael at Sports & Classic that the 996 Cup and 997.2 gt3 rs versions have been seen with stress fractures, potentially due the additional material that has been taken off.
I trust Michael so 964rs flywheel it is. Next decision, M&M full exhaust system or something more track friendly ??
FWIW to you or anyone else, I trust Mike too.Have been advised by Michael at Sports & Classic that the 996 Cup and 997.2 gt3 rs versions have been seen with stress fractures, potentially due the additional material that has been taken off.

For one thing, he' runs his own 996 GT3 that he's pretty handy with on track and has done plenty to. For another, he - like other decent indies out there, such as RPM, Fearnsport, 9e etc. - fixes an awful lot of other people's misfortunes/fk ups with the 996/7 GT and turbo platform, week in, week out. So he's got a good grasp on what does and doesn't fly.

TBH, the original 964 RS item is about as light as you need to go (certainly for road driving) in my experience. I doubt the additional 1.3kgs weight loss makes that much difference, and clearly nothing like as marked as going from a dual mass item to the original 964 RS item.Have been advised by Michael at Sports & Classic that the 996 Cup and 997.2 gt3 rs versions have been seen with stress fractures, potentially due the additional material that has been taken off.

Here's the difference between the original 964 RS and the late 996 Cup/997.2 GT3 RS item :
My guess is that the visible machining to the back isn't the only weight removal, ie I suspect some thickness has been removed from the section between the crank mounting boss face and the section where the obvious pocketing begins.
I have a dim memory that the 997.2 RS flywheel also has a bit of the inner mating clutch surface machined away meaning that not quite all of the clutch material is actually in contact with the flywheel.
Regarding longevity of the 964RS flywheel, mine is still going strong on the 996 after 150K+ miles so no worries on that front. I can't imagine anyone who has experinced both ever wanting to return to dual mass - you don't buy a GT3 because you're looking for refinement! Cup cables will transmit a lot of gearbox noise into the cabin both at tickover & when moving off. Passengers occasionally comment on it but I've tuned it out over the years.
An alternative to the RS pulley is a SuperDamper - I run one on mine & it works well. Needs servicing though...

I'm running the 964 lwfw in my 996 GT3 mk2. All the benefits as mentioned above. No issues with stalling or anything - treat it like a normal car when manoeuvring around.
Hi I. Once the ECU has adapted, and with it the idle stabilisation control, it should indeed behave completely normally. I'm led to believe the Mk2 ECU is different/more powerful than the MK 1 item, and thus may be better equipped to adapt quicker. I know one of my Mk1's took along time to adapt after the fitment of a CS flywheel, and during that time, things could get pretty smelly as the clutch got overly hot whilst trying to manoeuvre the car ...

However come to think of it, if I recall correctly I may have had some stalling when I picked the car up but it settled soon (I assumed I had just got used to it). Nowadays it is not even something I am aware of over any other car.

One thing I have noticed as a bit of an aside, is the stock 997.2 RS FW is a lot noisier/chattery on tickover than the stock 996.2 GT3 item.
Would concur with this. The FW itself doesn’t actually make any noise as far as I know, it’s the transmission etc. Gear cables make a difference too. Cup cables move the noise primarily to the shifter. Road car cables leave the noises behind you. It’s obviously noisiest where it’s slackiest. LOL. I like the look of this, if anyone is looking for something unique.

Get the OE wheels refinished in silver with diamond cut rims or a set of LM's or perhaps some gold centered E88's ...
