Why fit an S/T Clutch and flywheel to your 992 GT3
What is a clutch and flywheel?
The clutch is disc that controls the engagement of the power from engine to gearbox. The clutch cage is made from steel, with the clutch face itself made from a mixture of organic materials. The flywheel’s job is to smooth out the vibrations from the engine and to provide a mating face for the clutch to bite onto to transfer power from the engine to the transmission. The flywheel is a beautifully engineered and balanced, but relatively heavy component.
What is different about the S/T clutch and flywheel?
The Porsche 992 S/T released in 2024 has an ethos of providing the driver with the greatest possible, road focused, driving experience from the 992 series of 911 GT3. They managed this through lower vehicle weight, less complication (such as rear wheel steering delete), and enhanced road dynamics. The S/T utilises a lightweight clutch and flywheel. We have been fitting lightweight clutch and flywheel packages to Porsches for over twenty years, so the technology is well proven. Most race Porsches with manual boxes utilise a lightweight clutch and flywheel. To lower the weight from the flywheel, it is converted from a dual mass flywheel to a single mass arrangement.
Why make them lighter?
The lightweight clutch and flywheel for the 992 GT3 is 53% lighter than the standard Porsche equipment. Making a clutch and flywheel for your Porsche lighter means that the throttle response across the rev range is more immediate. As the rotating mass is reduced, the engine will speed up and slow down faster.
How does that make driving my Porsche more fun?
When driving your Porsche, as you come on and off the throttle the throttle response is more immediate and precise. Because you have lower inertia, the engine picks up better, and you can feel that extra responsiveness through the whole rev range. Secondly because the revs rise and fall faster due to that lower rotating mass, it means that when going down through the gearbox using the ‘heel and toe’ technique to rev match, the changes can be completed faster and smoother creating a quite magical ‘throttle blip’. All of which is rather technical, the reality in terms of ‘driving feel’ is it means the car feels more alive in its responses to the throttle pedal, and whilst it doesn’t give the car any more power, there is a feeling that it does! Mid-range acceleration from 4,000 rpm to the redline is noticeable more responsive.
How do you fit it?
It is possible to undertake the clutch and flywheel upgrade to any manual 992 GT3. This work is completed at our workshops in Long Marston near Tring, by our experienced Porsche technicians. The transmission has to be removed from the car to facilitate the conversion, so your GT3 will need to be with us for two days for fitting. Once completed, we will undertake an extended road test before final sign off.
What are the downsides?
Running a single mass clutch and flywheel means that slightly less noise and vibrations are damped out by the flywheel, which is most obvious at idle where you get a mild ‘chuntering’ noise. The clutch articulation requires a little more finesse as it bites faster, but the pedal has the same weight as a standard system.
