The story goes that as the clutch disc wears it gets thinner and the geometry of the fingers actuating the clutch plate changes. You effectively get out of the optimum range of the springy fingers.
I have a hard time believeing that a millimetre of wear changes the geometry that much, but I've heard this stroy a few times now, and there's no doubt that the clutch gets stiffer as it wears, so I guess it's true.
In the back of my mind I'm thinking the geometry of the 996 clutch may not be ideal from new, so only a little wear is enough to make it stiff. My clutch grabs pretty good, but it's stiff (no it wasn't sudden). I'm thinking that only a friction disc change will be necessary to restore my clutch to like new.
I say this because a bunch of us attended a tech night where the clutch, flywheel and IMS bearing were changed on a club member's car. She was complianing of a weak clutch but it looked like new when it was removed.
