I posted this on the Z3 side but curious if my s54 brethern have any input

The clutch on my 01 M Roady is starting to give way, actually I think it's the self adjusting pressure plate (only 44k on the clock btw). So I decided to scrap the OE pressure plate and use an aftermarket clutch kit, that landed me at UUC then the LTW flywheel bug bit me. Humm I thought it made sense more weight from thier clutch setup will be offset by the flywheel. The cost of a new stock fly wheel seemed way to high, ~800. So I pulled the trigger and order the LTW flywheel and upgraded clutch assembly. I have the tranny off, waiting for UPS to arrive today and now I'm having doubts.

I fear that the Twin mass stock setup may have helped some crank vibrations and by taking that out of the equation I'm introducing vibration, though the harmonic dampener should absorb it I wonder if it'll be enough.

on a side note I did find my oil leak, it wasn't my rear main but an oil pressure regulator on the side of the blcok.

Any thoughts?

UUC had a special fluid mix that was supposed to help majorly reduce (if not eliminate) the chatter.

The chatter isn't really my concern, it's possibly of reduced harmonic dampening on the crank and engine life. The Harmonic balancer does 95% of the work, but it's the little bit that the flywheel does taht concerns me.
