I know the dual mass flywheel purpose is to make first gear engagement smooth so you don't wake the family on long road trips.

I just removed my flywheel but as I was removing it, I noticed that the two halves will counter-rotate with each other almost a quarter turn, well maybe 1/8th turn. You guys know what I mean?

Which means that from a dead stop, you drop the clutch, you're standing still even with the clutch engaged for a split second until the slack in the dual mass set-up is taken up. Of course it's a lot quicker than that. I wonder what if I went with a single mass or even a lite weight flywheel. Just thinking out loud here.

I think it was audiholio or gigidy that got the RS4 flywheel and is having shuttering. I wonder if the RS4 flywheel is a single mass?

I opted not to go with an aftermarket flywheel because I don't want to give up my daily driveability, but man o man, that flywheel is every bit of 38lbs claimed weight.

Try your post on the 2.7T S4 forum as they try all sorts of stuff we tend to avoid.

Problem is unique, It's not a shudder due to clutch design. It feels as if the face of the flywheel has a raised section.

My advice, stay the hell away from light weight FW. You will take some parasitic load away from the engine, but a 4400# car is gona make that LWFW chatter like crazy. The slak you speak of, miliseconds.
