Apart from the vibration, did you like the feeling of a 10lbs flywheel? I don't.
uh, after you fix your balancer and rod bearings, I go back to stock setup with an uprated clutch. what's not to love about a lighter flywheel? Just sucks the S54 simply doesn't like them, at all. If you are dead set on a lighter flywheel, then go with the clutchmasters steel flywheel and a FX300 sprung hub clutch, otherwise get a rigid hub FX300 clutch kit and go back to the stock flywheel.

Default Re: Have you change your harmonic balancer on your E46 M3?

so with a stock flywheel, how often should we be replacing the harmonic balancer as preventative maintenance?

also, anyone have a link to the tool for holding the crank pulley?

i think you mean part# 83300493843, the one you listed is for an E31 wiring set, and is a good bit more expensive

and i believe i saw somewhere that the maint interval for the harmonic balance is 100K miles

I think if you track the car a lot you should do it before 100k cause they seems to melt-split around 100k

Mine melt at 105k.

It's an ''expensive'' part but it can save A LOT of problem in the end...

Also, i think vibration isn't the only issue. My car is a 2002, it's a 9 years old car and rubber isn't new anymore. And heat also destroy them. I think it's a good idea to duct some cool air to the damper.

I have 5 track seasons on my jb flywheel with zero issues. The s54 revs much quicker with less rotational weight as would any engine. I have a 3" duct venting mine since last season as I have heard of this issue popping up but only recently which leads me to believe that the failue has more to do with age and mileage. The rod bearing upgrade is on my list of things to do soon but I wouldn't be afraid to run an aluminum flywheel. If you have a track only car and compete you have no choice but to do all of the mods the rules allow to be competitive. Just my .02
