Question Clutch & Dual Mass Flywheel : SACH's, LUK or Genuine?

Whats up guys,

Looking to get advise on parts prior to diving into planned:

New: Clutch
Flywheel


From great previous threads : LUK seems the go -to & OE maker of the Clutch / and DMFlywheel. The "clutch kits" by LUK may possibly need a genuine part throw in to compensate from what I am getting.

SACHs always a quality brand - anyone prefer to use this clutch kit over LUK?


As far as DMF, I gather its debated on replace vs not. I'm going to do so, because "While in there." But also don't want to drop trans again to replace down line (10-20k). Is LUK regarded as the go-to DMF for you guys who have replaced?

Mainly looking for guys who have been running these parts now for the long haul trouble free. Or if any issues, pls advise as any help would be greatly appreciated!

Figure, id start this as a new topic because I haven't seen any recent threads on this and not sure if anything has changed.

Cheers!

I installed the LUK clutch and flywheel. Works as advertised.

The only difference I can tell from the OE and the LUK unit is that LUK has a bit more chatter in the lower rpm's. That's it.

LUK clutch, pressure plate and DM flywheel, OE pilot bearing, and Sachs throwout/release bearing

20k miles on it and happy with the setup.

Clutch disk and pressure plate are the same between both kits.

Throwout bearing: The Sachs is what the car comes with from BMW. The LuK is different but still a perfectly good and reliable part.

Pilot bearing: The Sachs kit does not include one. The LuK kit includes a garbage one. Use a genuine BMW (NTN, Japan) bearing.

Back when I did my swap I had done enough research to know that the LuK throwout bearing was not OE, but I didn't know about the pilot bearing and used the one supplied with the kit (I think it's Korean made).

10k on it now, no issues. While one can worry that this pilot bearing may be overall less reliable and may not last as long as the OE pilot bearing, are there any known horror stories about these failing? What happens when a pilot bearing fails, anyway?

I tried a couple before I immediately started throwing them away. I found the outer diameter is too small and the pilot bearing will not seat into the crankshaft. I was concerned that it could "move" and either wear the bearing surface or jam itself into the input shaft or crankshaft causing failure.

Did you use the LUK pilot that was included in the kit?

This is awesome! 20k is healthy mileage and looks to be the go/to combo. Hard to say no to SACHS.

For what it’s worth, the Sachs clutch kit I bought still came with a LuK throwout bearing, much to my annoyance. Seems the only reliable way to get the Sachs bearing is to just buy it separate through bmw.
