normal, completely normal. 10x worse on my e46 m3 and everything is in front of you...

 

Wouldn't a heavier steel one be quieter then a aluminum one ??

 

I think being single mass is the problem. The dual mass balances out the vibration. I think a steel one may reduce the noise a little but will always be noisy......not even sure if one is even made for our cars .......can't be that much savings in weight compared
OE Dual Mass : 32.8 lbs (from pelican parts)
LWFW : 14.5 lbs (from pelican parts)
I don't see a single mass steel wheel any where listed.

 

I believe it is a Porches RS factory one,, also I think Sambo sells one and Kevin from UMW uses that in his kits because they are quieter?

 

Not knowing the design of the ring/flex gear on a TIP, would the mass on a TIP input shaft be more or les than a LWFW? This would include the TC and the rotating components. My TIP rattles..
