    I've had this installed for about two weeks now. I'm satisfied with the purchase. The kit does chatter. It was louder when I first installed the clutch but it seems to have quieted down a bit. Still pretty loud considering its not a LWF. There are no clunks or any other odd noises. It's smoother than the stock clutch for me and the car seems more eager to rev now. Clutch does grab pretty high now but that might have just been how the install was done.

    Funny, mine grabs incredibly low (I admit my old DMF was engaging super high, so my perceptions could be a hair skewed). I agree it’s smoother to drive, but my car sounds like an old diesel at idle, which is a very big con for me.

    This line of text will be replaced in about an hour with a link to a video I took today of the chatter.

    You can hear me cycle through depressing and releasing the pedal in the video. Botond confirmed his sounds just like it—his was installed by a shop, mine was installed in my garage with a great deal of swearing. I’ve pointed out these install differences multiple times because I think it’s an important independent variable in an experiment with identical results.

    Fwiw my Eastern Bloc transmission guy said the same thing...

    Oh fudgsicles

    I think there would be more swearing after installation.

    I am tending to gather that there may be many variables (e.g., installation, drivetrain condition, suspension condition, etc.) that impact how a new clutch performs--hence all the different results.

    Interestingly, the shop that installed mine said quite the opposite. I was told they install them all the time, and that they all chatter, in various model BMWs as well, not just in the E46. I was desperate as my throwout bearing wasn't even a bearing anymore so I had to proceed with the install anyway.



    As far as the reasons go, I fail to see how installation could possibly affect this. It only goes together one way. Could somebody please explain?

    I’m sorry but I’m just not buying it. I changed one thing and my drivetrain went from being completely silent to sounding like a tin can full of marbles. Scientific method. Independent variable.

    Not to mention everything drives way too friggin’ smooth for me to have even an iota of doubt that something wasn’t put together correctly.

    Correct. There’s only one way it goes together. If you can drive it, it was assembled correctly.

    Your shop is wrong, because mine doesn't chatter whatsoever--thank goodness, because nothing irritates me more than chatter and rattles. As far as causes, a quick google search yielded the following:

    - oil contamination of the disk
    - heat build-up due to excessive slippage
    - bent diaphragm spring
    - missing or damaged pilot bearing
    - bent flywheel (possibly related to aforementioned heat build-up)
    - damaged or worn out release bearing

    Of course, "clunking" of the drivetrain can be caused by a bunch of other issues.

    .
    I don't believe these are reasons it may cause such issues in a brand new installation as all of the mention parts (clutch disk, pilot bearing, flywheel, release bearing) are brand new parts included in the kit. Things like oil contamination, heat build up/slippage are also unlikely for the same reason. I don't know what you mean by "diaphragm spring".

    Two manual ZHP's that I had and few others that I test drove, all around 100k miles had chatter at idle with original flywheels, but not as loud as your current one. I can see how annoying this is for you, it would drive me mad.
