Hi,
Starting to assemble new suspension, and wanted to check something with the strut mounts. The Z4M mounts have some rubber nubs that are preloading the big washer that sits on top of it. Is that intended, and do I just tighten it up that way, or so I have a wrong part number somewhere (and it should be a smaller washer). I checked on RealOEM and the part number is correct, car is not here right now so I can't check what's on at the moment.
You can kind of see it in the photo below:
