Just out of curiosity and I know Jim already asked, but how do you know that your flywheel needs to be replaced ? Was this something that the PO told you?
I have a friend that drives a 993 and had his clutch replaced by Autotherapy. Roger at told him it's usually not worth resurfacing a flywheel, better to go ahead and replace.

I test drove a lot of 911's before buying and the clutch action seems weak compared to the others.

I reviewed the service history paperwork and I see no instance of any clutch/transmission maintenance. Is it normally included as part of a major service?

It's worth resurfacing unless you like to spend money. But dual mass flywheels (993) you cannot resurface. There is no way to anchor the clutch side flywheel to do any machining operation.
Doing a clutch is not part of a major service.

Weak (slipping?), just light force required to actuate? Bad clutches usually require more pedal effort, not less. And the hydraulic clutch of your G50-equipped Carrera should be lighter than the mechanically actuated clutches on older 911's. If your clutch isn't slipping, enjoy your new car.

Dual mass flywheels make excellent boat anchors. Have any of you guys ever held one? Yikes!

I am just going to drive it until such time it doesn't move.

Howard, I'm confused.

Is the clutch slipping (i.e., car not moving)?

Is the clutch pedal what's not moving?

It is not slipping but it does not feel rock solid. Also when I am in reverse I have to give it more throttle or it wants to stall.

Maybe I need someone with more experience with a G50 to drive it and see how it feels.

Come by the house this weekend. Do you still need the lights?
I don't have a G50, but have worked on numerous hydrolic clutches.
Like your brakes they could need bleeding. Or you could have a bad master cylinder, slave cylinder, or it may be a simple adjustment. Could be leaking. I would imagine the adjustments (If not self adjusting) are simular to other cars. (anyone got a carerra manual?)
Fisrt thing to do is see if the clutch itself slips in higher gears. That would indicate a problem with the clutch springs itself. The springs are always putting pressure on the disk except when you are depressing the pedal.

The pedal releases the clutch via the hydrolic system. Usually if there was a problem in that part you may have problems shifting, but not necessarily slipping. This is most of the time, but it's possible that it's way out of adjustment or binding and not allowing the springs to do their job. Best way to check this is to watch it in action from below the car. Someone inside and someone watching.

As for feel, my guess is that it feels more like a toyota as opposed to older porsches that use cables.

Bill there is no adjustment. But your other comments are spot on.

Having owned both a g50 Carrera and 915 cars I really liked shifting action of the g50, but the pedal feel of the cable clutch. After a bleed of the system it did feel better, but still seemed isolated when compared to the cable operated clutch.
