  • Best motor mounts

    OK... what is the current suggested optimum motor mount for our car. 2.5, street/track/autox
    It still appears to be 740il mount but I would like to see if there are any other new ideas.
    TIA

    group n mounts but $$$$ compared to stock. I will switch to urethane pucks on my race car. Also for the gearbox since my rear end is now solid mounted

      Gruppe N is too rich for my blood. Definately the ideal answer but ouch...

        For a road car just stick to standard, or do the 740 mounts - do a search and you'll find plenty of info on this upgrade.

            I'm running Ireland urethane mounts on mine. 2.5L/Street everything seems good so far. They're pretty stiff, but don't seem overly stiff.

              I'd 2nd the Ireland mounts, the people I spoke to with them didn't think they were overly harsh or anything

              IMO even the 740i mount is too soft for anything but a 2.3L boulevard cruiser, you will get a lot of engine motion with them, especially with the added power

              You should think about doing the trans mounts at the same time too, same source.

              edit: oops, I forgot that you are already looking for tranny mounts too :borg:

                Urethane actually is a better absorber of vibration than rubber/fluid is. They have different frequencies and damping characteristics.

                It all depends on what you want to achieve/

                  Hey Dreamer,

                  What did you use to shim up the IE motor mounts? Really big fender washers maybe? TIA.

                  To answer the original question, I've stated this before: the IE mounts are at least a 1/4" shorter than the stock mounts. Shimming is required. I'm just not sure that using any old thing laying around the garage is adequate.

                    I'm willing to bet that old, worn out factory mounts are sagging a whole lot more than that

                    I wouldn't worry about it, but that's me ....

                          Dietrich,

                          I'm running them as is. Ireland's website indicates they are shorter, but provide more clearance. I haven't noticed any problems so far and I've been running them for about a year.

                            Interesting... This weekend I went to the local h/w store and bought ten 2" (3/8" I/D) fender washers. Maybe I won't need them.

                              I was told the 740 mounts lower the engine which then will add stresses to the driveline because the angles are changed.
