Quiet Lightweight Flywheel?

[D-O]

Sreten of M539 restorations used a lightweight (~ 4 lbs. lighter than stock) dual mass flywheel from PTB Racing on one of his cars. Skip to 16:40 in the video to see it.

That's awesome, but a custom built one probably costs more than I'm willing to spend.

BBRTuning Isn’t your single mass fairly quiet?

I forget the brand, it was made it the UK, got it though Matt as Euroconnex. Its for my E63 M6, so not the same, but replaced a dual mass and I have zero NVH issues with it.
I *think* they make one for the M3 as well, but who knows if it will act the same.

I have a JB Racing flywheel. It sounded like marbles in a glass jar with the 420g. Mostly quiet with a ZF320 although the car has always been a tin can with the ZF320.

The rattle might have more to do with the transmission than the engine.
