    M5 flywheel swap

    So I need a clutch, and I got an M5 flywheel sitting in storage.

    Do I need to mix and match parts to make this work, or can I just rock any E28/34 M5 clutch setup and I'm good to go?

    Thanks,
    Erick

    I believe m5 flywheel is same as the 533....what tranny are you using? That dictates somewhat if the e34 clutch kit would fit from what I gather.

      I'm using the e28 535iS tranny.... one of the Getrag 260 models. (Dunno what the 260/6 is)

        260/6 has horizontal fins on the lower section. 260/5 does not.

          Same transmission I have. I'm using a e34 m5 clutch and flywheel with stock e28 everything else except the e30 slave. It is stiff! (no homo)

          edit: I have an m5 pilot bearing thing as well (thing that goes in the middle of the flywheel to center the input shaft)

            Then I have the 260/6.

            Is the pilot bearing necessary?

              No idea. My engine was originally from an auto so I had to get a new one anyways.

                Yes you need the pilot bearing, just buy an e28 535 clutch kit.

                  That works with the M5 flywheel?

                    pilot bearings are all the same. It basically locates the input shaft of the transmission so it doesn't wobble around. It has nothing to do with what clutch you run. If you buy a complete clutch kit, it should come with one.

                    I didn't replace my pilot bearing because it was pressed on there like a mother from the factory. If yours isn't making noise or causing trouble, don't worry about it.

                      I think he means does the e28 clutch kit work with the m5 flywheel.

                        e28 535i clutch kit, but yes.

                        I'm ready to go with an M5 clutch, just because I've seen it work.

                          Hey just curious so, jb sells the e34 m30 flywheel for $630 and sells the e34 m5 for $497?? I know its cheaper cause its a replacement for a single mass flywheel, but if im about to buy a new flywheel/clutch kit for my car (M30 B35 getrag 260/6) then I shouldnt have problems with fitment with the m5 flywheel right? although my m30 clutch wouldnt work?? Thanks alot

                            so i assume you are using the m5 Throw out bearing?? or is the throw out bearing part of you "stock E28 everything else"?

                              e28 t/o bearing. No noises from that, but my slave sure isn't happy.
