I still don't get why people have issues with the vibrations. I've got a 95 duro rear mount and it really doesn't bother me.
personally I think replacing MSP motor mounts with "OEM duro" is about as smart as mazda using the same engine mounts for the 2.0l Mz3 that they use in the MS3.
Bad engine mounts are a major contributing factor to diff failure... and adding a little cabin vibration is a small price to pay for better shifts, cleaner power application, and most importantly MORE RELIABILITY.
i get insane vibrations when the ac is on and car is rolling in neutral. you can actually see the dash going up and down. otherwise they're not that bad.
