I recently installed factory Cabrio / Club Sport engine mounts (higher durometer rubber than original coupe mounts) and WEVO black transmission mounts on my 1987 mildly wife unfriendly / "Club Sport" M491 build.
It feels like a good setup for a slightly more sports purpose feel.
I also have a spring centered clutch disk and a WEVO PSJ. There's definitely more vibration transmitted through the shifter with the new engine / trans mounts. I'll swap the stock shift coupler in for some A/B testing.
