I ran the black revshift motor mounts for around 3,000km. Mostly street driving and one track day. The mounts I used were the ones that were marketed as street or oem+ on fcp.
Didn't like them even with the idle set to 1k rpm. Car felt a bit better with the revshift mounts but I'd say it was fairly minor in the grand scheme of things. What was not minor was the added vibration at idle. It was quite noticeable, and this is with a bunch of other NVH-adding mods having been done previously which probably helped mask the overall NVH from these mounts (coilovers, poly trans mounts, solid mounted rear subframe, twin disk xclutch with all the jingle, and minor things like m3 arms and monoball conversions).
I'd only recommend these mounts if NVH considerations have gone out the window. Straight pipe or hood exit, gutted interior, solid mounted diff - that sort of stuff.
Have since thrown in some stock mounts, so if anyone in Aus wants some lightly-used revshift mounts, let me know.
