Just a heads up to those tracking their N54s running black revshift motor mounts and stock/race catted down-pipes. I ran this mount on the passenger side with the heat shield and kept the drivers side stock. We found the mount had melted significantly +3 months after installation.
Vendor has now explained that the green poly can handle more heat, and is recommended for track use. A higher temperature black poly is also in development...
The simplest way to describe how a melted mount feels is "settled". Ie NVH is reduced. Those vibrations you felt in the beginning are gone? The car doesn't feel as direct to drive anymore? OK, the poly might have changed shape due to melting. Please have the passenger side mount checked to make sure.
As a temporary solution I am now running green poly on top and black on bottom. Only the top half had melted. Driver's side is still stock. NVH with this setup isnt too bad, and the responsiveness is awesome...
