Even with a lift, the engine mounts require a lot more work to swap out. Many other items need to be removed/disconnected, the motor must be lifted, and even then access is difficult. The other two mounts are basically there for the unbolting without much of any work.
The Group N tranny mount is basically just an OEM mount that is filled in with rubber. I had already done this with my stock mount using 3M window weld (durometer of ~60). It didn't really make any difference from what I could tell. I expect the Cusco mounts will be a pretty noticeable change.
