Clutch Question
2001 986 S 100K miles
My clutch has starred to shudder a little when i move from a standing stop, is this an indication my clutch is end of life? No slippage, just a shudder that wasn't there before.
Planning to change it in a month so I am hoping I have a little life left is this is the case.
Anyone want to weigh in?

That's what mine started doing a couple weeks before the clutch gave out.

Thank you sir...I posted this hoping you would weigh in. Ill shop the parts now and guess Ill do all the "while your in there stuff to, such as RMS and IMS.
Should I replace the pressure plate also? any advice you care to share on on other stuff?

Most clutch kits come with the pressure plate, throw out bearing and pilot bearing. The Sachs kit I bought from Vertex Auto was $295 shipped and also included the spline grease and alignment tool.
Definitely do the RMS and check the flywheel.
It's a fun job. I thoroughly enjoyed it

Better than 50% chance that you should replace the flywheel as well
stay with the dual mass flywheel and not a lightweight flywheel

The flywheel is used to balance the engine .it is not your typical flywheel it is a two piece assembly that is spring loaded against the two parts .

So, I answered my own question and will talk about it.
Its a dual-mass flywheel with some "action" to it, resurfacing might restore the wear surface, but that shuddering could be my flywheel giving extra, and now that I think about it, that is EXACTLY what it feels like.
This video set me straight:

The stock flywheel is a dual mass flywheel, and dual mass flywheels shouldn't be re-surfaced. Just replace it while you've got it all apart.
