I missed a lot in the video.
But basically. The 60a is only slightly better than oem. Just with induced vibrations.
The 75a is much better than the 60a perforemance wise but the vibration is noticeably worse, however not much worse than the 60. The real difference is in drone.
The 75a drones much worse than the 60a.
I wish the 75a did not drone so much as the vibrations are very similar to the 60a and they perform much better.
I believe the 75a break in to feel like 60a(new). The 60a will probably be too soft once broken in.
I think mixing the two durometers is the best option. The driver and front mount is very hollow on the crx, Maybe they transfer the most nvh of the four mounts. The rear torque and passenger are the beefiest and probably do the most work and transfer the least vibration.
Variations in reviews can be impacted by chassis stiffness and mods.
