At that point might as well do a lightweight flywheel a new clutch and upgraded csc or csc elimination kit.

IDK either. Just reporting what Ryan has discovered. Could be that a bad lot of pressure plates were installed on certain vehicles during a production run. Again, IDK. Agree that changing the CSC is no big deal. However, it only adds to the cost of the repair. It'll be interesting to learn what the OP discovers at the dealership.

Don't worry. Mine does the same thing. I feel it at idle. I know it is the pressure plate. I am going to drive it as far as I can, then do a total upgrade. I get feedback from the clutch with the pedal depressed and I hear a clicking sound and feel it in the pedal. I don't always get it. I will guarantee one thing. I will fling that dual mass flywheel across the yard. Told the dealer about it and they were not helpful at all. Hence I told them I would yank that junk out and put a proper clutch, flywheel, and CSC setup in it. Basically, to shove it where the sun don't shine, they were not getting any of my money.

Parts guy I have bought mucho parts from says he keeps a clutch/flywheel on the shelf for the 370z so it is not uncommon.

Well, that thing is so heavy you won't be throwing it very far lol. A lightened flywheel was the best mod I did to my Z!

LOL. I also love a lightened flywheel.

How is the clutch chatter? A buddy had a lighter flywheel on his 350z and the chatter was annoying:ugh2:

you nailed the problem i have... a bit of a 'click'/knocking i feel and hear... i notice it happens only in certain conditions like on a hill with the nose pointed up the hill (like on my drive way or incline) and also sometimes on flats.

I guess it's a sign that my clutch is worn possibly? clutch fluid is still same colour as when I got the car but I do check weekly when driving... I am debating do a pre-emptive strike next year and do the CSC + switch to a new clutch system.... depends on the wallet :shakes head:

The level of chatter is somewhere between "F250 Diesel at idle" and "Something sounds broken". :rofl2:

A lightweight flywheel is absolutely worth doing, just know that there are drawbacks.

Personally, I think it is a defect that should be covered under warranty. I didn't get anywhere at the dealer though. So, oh well. Still not happy about it.

^^^^this^^^^

Thought I had mine licked today. I changed the tranny fluid last week when I did my 30,000 mile service. It was quite all day. Pulled up in the garage at home tonight and what do you know, it was back.

Resurrecting this. Did the OP ever discover what the problem was? A number of suggestions were offered, and supposedly the vehicle was being taken to the dealership. If so, what did they discover?
