So, I read through some of the posts in that link. I am having the vibration too, associated with the noise, which, I know is normal. Is the vibration normal too?

... are you hoping for somebody to tell you there's a problem?
It's normal.
That's not to say zero damage is being done - but that's part n parcel of having a more aggressive clutch. Your gearbox will probably be under increased load due to the unsprung nature of the discs but I'm not sure if this will have a measurable effect on longevity or reliability.

This is normal. Just stay away from hard launches to save your t-case and tranny.

I heard it may be your throw out bearings.

Should've researched before you got that twin disk. Its the #1 daily driving complaint with twin discs.

OP - what did you think you were getting in to when you bought an unsprung twin capable of single digit passes...?

Wrong on many levels. There are no "throw out bearings" There is a throwout bearing, but in this case, it is a push style clutch with a hydraulic release bearing. There is NO THROWOUT BEARING.

The decel would appear to be normal. Personally I do not have that noise on my own Quartermaster Twin.
