Aftermarket Clutch and Flywheel Chatter/Rattle Poll
does your aftermarket clutch/flywheel combo make a rattling noise under 2k rpm? what the hell causes this? is there any fix?
If it does not chatter, what combo do you have?

i dont believe the chatter is from the throughout bearing, mine does it and it is stock. ive been told by two different stealerships that it is just a noisy input shaft and there is not much you can do about it.

mine chatters only below 1000 rpm so i voted yes...but i rarely get it. I have the ACT R6 solid puck/unsprung, with a prolite flywheel...but uh..that clutch is violent..but so so good.

^hes right. Switch to redline MT-90, and change the diff fluid to royal purple. Much quieter, no more shaking when rolling up hills or reversing. Cleaner shift also.

This was taken from another forum explaining why there is "clutch clatter". Here is the link....
<http://forums.vwvortex.com/zerothread?id=3359754>
you need to understand WHY a trans will "chatter", the clutch doesn't chatter with a LWFW, it's the gears in the gearbox that you are hearing.
With a heavy flywheel, there is enough inertia to eliminate the gear lash, because there is always a positive force on thee gears holding them tight against eachother.
With a LWFW, there is not enough inertia, and what you are hearing is the frequency of the pulses of the cylinders firing, and each time one fires, it pushes the crank, the crank turns the flywheel, then the input shaft and connected gears.
Think about 2 gears together, there is a little bit pf space between the teeth of the meshing gears, this space allows a little play, "lash", and the gears will "tap" whenever a force is applied.
SO, long story short, a lightweight flywheel, which doesn't have the inertia of a heavy flywheel, will not turn at a constant speed, and therefore the "play" in the gears allows them to slop around a bit.
But with a heavy flywheel, the inertia keeps it moving at a constant rate, even between cylinder firing, and therefore there is always a positive force against the gears, keeping them in contact with eachother.
