well, as 6speed and m54 was an option since facelift here in europe, there should be several usable combinations.

just have a loot at bmwfans to see the part numbers.

If you're getting the non-M 6sp that was mates to the M54, you options are severely limited. That box uses an input shaft spline that is unique.

I have the UUC flywheel/clutch. It's pretty good but does rattle.

Yes. Went with dual mass flywheel and Sachs race engineered performance clutch system. Many would say stiff clutch pedal, but the heavier the better, at least for me It was mated to a pre-facelift, but should fit all M54s. Let me guess, you found that 6sp pulled from a Z4?

I put a ZF 6 speed into my e30. its clutch compatibility is vast:

22 spline involute style is shared between a bunch of cars from 2004-2009:

e60 530i
e46 330zhp/325ci smg
Z4 3.0 and Z4 3.2M
E90 325/330i

common parts really; anyone can buy an aftermarket or OEM setup pretty easily

Are you sure the Z4M 3.2 input shaft is the same as the rest? Just because it's also a GS6-37BZ doesn't mean much. If it is the same, using a z4m pilot bearing should allow a much wider selection of flywheels

My understanding was that although the z4m has a 22-spline count like the other variants, the M has thicker splines (kind of like e46 M transmission compared to earlier S6S420Gs)

Z4m clutch is direct interchange with 135/335 and 330zhp also. I have mixed these all up and actually have a few setups crated up to ship overseas.

In my e30 I ran:

2006 zf6mt
335 turbo clutch
330zhp flywheel

Photos are on e30tech somewhere

If that is truly the case I'd probably run the Z4M pilot bearing (which is separate from the flywheel unlike all the other variants with the GS6-37BZ) to enable a much wider section of flywheels (Z4M itself uses the same flywheel as the E46 M3).

Unless you personally verified it though, I have my doubts. I remember reading a few posts on Zpost where it was confirmed the Z4M 6-speed had a different input shaft than the rest of the GS6-37BZs. I have no doubt you can run a 335 clutch with a 330 flywheel on a 320d transmission. But the Z4M gearbox itself is the wildcard from what I understand

I have a z4m flywheel here. It's the same standard as 330zhp; dual mass with needle bearing in it and 240mm self adjust style. 320d is the same 240mm standard. The e60 545i also shares this standard for pressure plate and friction disc iirc

The z4 3.0 has a flywheel/friction disc and pressure plate for 228mm

Most likely you have gotten mixed up on this issue. I bought a z4 3.0 full driveline/clutch setup as well so it was easy to compare

The pilot bearing is removable for all of them, you can order it via part number. Check real Oem if looking for it

Well since you apparently have all the parts on hand, I guess I'll go with your assessment.

I would like to note that the Z4M uses the same flywheel as the E46 M3 (same part number) along with the same pilot bearing as all the older BMWs (I was wrong there). But in any case, that led me to believe that the transmission side may have been different enough for BMW to use a different design (otherwise... why didn't they just use the same style clutch on the 330 6-speeds and stick with the old 5-speed flywheels? Guess we'll never know).

The new everything is revised, more efficient. New patented tooth pattern on the spline for gearbox, new style needle bearing pilot bearing in the flywheel; Trans input shaft is shorter now.

New style flywheels also are for self adjusting clutch setups
