    Motor Mounts

    About motor mounts, poly better than stock rubbers, yes? What about solids? Pros / Cons?? I don't intend to race but I do drive aggressively, sometimes.

    Polys will last longer but transfer more vibration and provide more stability. Solids will transfer all vibration and keep the motor the most stabilized.

    If its a dd I would go polymers, a Sunday cruiser or track car, solids.

    I just did mine when I installed a set of longtubes. I went with the poly mounts. Car feels much better and the vibration is really not that bad. Word of advice, I would recommend removing the pedestal bolts and pulling the entire assembly out as one piece. This way you will not have to move the AC compressor or alternator to get the long bolt that goes through the actual mount, you can just remove it after the entire assembly is out. Made my life much easier.

    I have thick hands, so I will try it this way.
