I have an ST4S with 32k miles on it now, still on the orgiinal clutch.
It is now making the same noise as my 996 used to when that had only 10k miles on it.
I've heard lots of reports of the various aftermarket options, and they all end up rattling at some point, just some quicker than others.
Have a read of this thread:
