On the stock mount the entire bottom is the bushing. Watch the video of the removal and look at the bottom of the mount and you will see. The Boomba mount has moved the only dampening to around the bolt holes that go to the transmission.
We just whipped together something for you guys here to show the difference between the stock mount and our mount.
You can see the stock mount has a huge sloppy bushing on the bottom of the mount. We've moved the bushing to where the bolts go, made it a stiffer durometer, and made it [the bushings] smaller. This results in significantly less drive-train movement.
We're working on a comparison video.
Sorry, we did not see your question.
Alrighty. Thanks!
In regards to NVH, this is now why we offer two different versions; a 70D race spec and a 60D street spec. The race spec transmits a good amount of all type of transmission noise such as the gears spinning and clutch engaging/disengaging. The street spec one is much more tolerable on a day to day basis. It really depends on what you want out of your car. People have said that the race spec on a car with an aftermarket exhaust is fine, but can be a little much if you're on the stock exhaust.
