Flywheel Advise

[M318]

Ok apparently I need to replace my dual mass flywheel every time a new clutch is installed says my bimmernut reputable mechanic buddy. I found this. What do you guys think? F1 RACING PROLITE 16 LBS FLYWHEEL http://www.allreplacement.com/product/1228

I dont have time to fuck around either. I gotta order something quick. I am sick of pushing my car in and out of my shop.

Its a great flywheel, I have one on my e36 M3 and combined with light wheels, will make a dramatic difference!  . Just get an E34 M5 clutch to go with it to cut down on flywheel clatter. Also, for fluid, use 1  bottle of Redline 75W140NS gear oil and 1 bottle of Redline D4 synthetic ATF and you'll be good to go

I just bought a brand new oem sachs clutch and pressure plate. Shouldn't I be ok with that? I got the 5spd zf also. So you are saying to mix those two fluids to put into my trans?

Yeah the OEM will be fine, the difference is the E34 M5 clutch is a sprung hub clutch, and that really helps cut down on clatter from the LTW flywheel. I 100% recommend that fluid combo! Made a big difference on my E36 for shift quality as well as killing a little of the flywheel noise.

shit thanks for the info. Enterprise motorcars soaked me 35 bucks for a used oil container filled with bulk diff fluid for my 318 trans lol. I can imagine what they would do to me if I asked them for trans oil...

Are you referring to the UUC one?  Whats the stinky on that?  Just curious as I have had one for a few years with no troubles.

Also the mixture of redline fluids is excellent, I have no gear rattle after putting that in with (e34 M5 clutch)

I dont think its actually been proven, but the rumor is that the lighter flywheel and increased rev limit has caused some bad harmonics resulting in catastrophic engine failure.

Oh, I am still using stock tune.  Is the UUC one worse than others?  I think a bigger issue is the super smart folks replacing the harmonic balancer with a under drive pulley.  I'm sure the flywheel is important but the harmonic balancer is what keeps the crank in one piece.
