  • Photos of Old Motor Mounts

    Here are some photos of my worn motor mounts, which I replaced a couple of months ago (the first photo shows the old next to the new).







    Cheers, Daniel.

      Street-only, but the mounts are probably the original ones, or something that has been there for years. My car had a rough life.

      I think that the motor mount (driver's-side) in the above photos was over-stressed due to the passenger-side mount being a non-M3 unit. I don't know what it was, but someone had cut off the lower screw and rewelded it. It is a lot shorter than the M3 mount. Here are 2 photos that show both of the old mounts, with the passenger one on the left side of the photo:

        Possibly it was a converted 740i mount.

          Good eye! That looks very similar. I suppose that one should use two 740i mounts together, and not just one of each as someone did on my M3.

          Cheers, Daniel.

              No wonder when I bought Marie-Chie, Jacie & Apex Eng. mentioned that I would not be able to install the fan shroud because the fan would be hitting the shroud no matter how I would have it fit on the mounting holes on the radiator. Now, I know why...P.O. had the 740i mounts. Is this good??? Still learning all of the ins and outs of a M3.

                I didn't bother to read the whole thread but I believe the 740i mounts will lower the motor about 1/4", which will essential lower your center of gravity. By lowering it, those with the mechanical fan will no longer be able to use them.

                  Make sure the heat shield is also still in place on the PS otherwise the mounts will fail prematurely due to heat.

                    Looking again at the photo of my old passenger-side mount and comparing with the photos on Gustave's site, it seems that I did not have the 740iL mount. The 740iL mounts have the lower screw in the center of the mount, whereas my mount has the lower screw off-center.

                    I am still curious which mount was used. Also, I need to check this more carefully, but I believe that since the lower screw was off-center, the installer had to widen the mounting hole in the arm which connects to the motor from the front subframe. The problem I have now is that the new M3 passenger-side mount is a little squashed (see the following photo):



                    I have a new front sub-frame, and I will order a new passenger-side motor mount arm, which I will install in the future.

                    Cheers, Daniel.
