I installed one today, along with a Barton shift bracket, and man I can really tell a difference in the rigidity of the driveline. I knew there would be an increase in NVH, so I guess I am being over sensitive to the noises I am now hearing.

When initially installed, the noise was a little much for a daily driver so I did the mod with the center section of the mount. While it is much much better from a noise standpoint (the rigidity of the driveline was unaffected by the mod), I am just being paranoid and want to see if anyone else has experienced the same. Clutch in, while in neutral, all is quiet. When I release the clutch, I hear the driveline. I'm assuming it is the internals of the transmission. And of course I hear/feel while accelerating through the gears.

Is this normal? Shifts feel much better and I would like to leave it for this reason.

 

Some clutches are inherently noisy, or the slave cylinder gets that way. Mine is like that when in neutral, and I don't worry about it.
