What issues, besides the rattling noise, if exist extra "issues"? I would like to know.

The issues raised thus far are whether addtional vibrations can occur along the crank , thereby reducing reliability .

Our flywheels are chrome moly billet and are balanced , so , assuming all of the other components are also balanced , this issue shouldn't cause unnecessary concern .

I have had a 4.5kg flywheel fitted to my 3.8 saloon for over 4,000 miles now , having covered 144t miles on the original crank and shells .

Time to upgrade to 3.6L M5 clutch seems. My car is finished and took it for a spin. After few pulls I noticed the clutch started to slipp at 3rd and 4th gears. So the dualmass flywheel must go among the PP and disc.

Most likely I will go with OEM route so, what exactly do I need to swapp succesfully my clutch/flywheel?

What parts do I need form this diagram...

1 , 3, 4 & 7 or all the parts? I would liek to avoid buying everything, but if needed, well so it be.

Clutch BMW 5' E34, M5 3.6 (S38)

and here

all the numbers or just few?

1,2,6,7,8,9,10,11

Twin Mass Flywheel BMW 5' E34, M5 3.6 (S38)

Thanks

Hi Diego ,

Why would you choose to go with a 5.7 kg standard 3.6 smf over a 4.5kg chrome moly billet smf for less money ?

Either way , you need a 3.6 clutch kit i.e. pressure plate , friction plate and release bearing ,fillister screws and sleeves and the 3.6 flywheel bolts .

Hi David,

not sure if the lighter would be OK. How much goes the chromolly unit? I guess shipping it from euro to south america would kill any deal.

Thanks

I have no rattles with your flywheel D. As my gearbox has been rebuilt & my clutch is new that leads me to conclude that any rattles are gearbox related & nothing to do with the flywheel.

There is ZERO delay in the throttle action now. It revs much quicker than before & with Alpina digital clocks I can see that as the revs rise so does the oil pressure.

Thanks for the feedback.

Anyone knows if there is any PP & disc that fir the 3.6L clutch not OEM and bit cheaper? Or where is found this clutch in other models? Perhaps the 535i came witht he same 240mm clutch setup? I ask this because I have a big shopp here of clutch discs/PP that sell a lot but they don't have a sophisticated data base if I provide e34 US 3.6L VIN and check for the correct clutc/PP setup for this conversion. If this setup is used in other plataforms, maybe I have a chance to source a junked one downhere and with it, the shopp can check for a identical one.
