Innovative Motor Mount questions

I agree with Billman250.
When my engine was replaced, we replaced the engine and tranny mounts as well with Innovative 75A Track (Black). They have four stiffnesses:

Major mistake! The car had two bad resonance points, one at 15-1800rpm and one at 39-4400rpm. At those engine speeds, the car felt like it was gonna shake itself to death.
I drive 25,000mi a year, mostly either in stop and go traffic (15-1800rpm) and at freeway speeds (4000rpm). Couldn't handle it. It sort of felt cool and all, but I never heard so many things inside my car shaking around. I have no doubt that another downside of this would be a huge increase in rattles and noises and vibrations inside the car as time goes on.
They felt cool at the track, but it ain't gonna translate to faster lap speeds.
So, Innovative seemed to indicate they hear this many times. Since they have a lifetime warrantee, Inovative gave me their 60A Street Red mounts which they said was about the same as OEM. And it is, perhaps a touch harsher, but maybe not. Very happy with them. Had to pay for the trade out in labor though. My mech lifted the car and then put jack stands under the engine.
While they do have a lifetime warrantee, Innovate freely admitted to me that the 60A Street mount will not last anywhere near as long as OEM.
If I had my choice again, I'd go OEM, as long as I got a good discount.

Tolerance to NVH is very subjective and opinion based. Bottom line is, it's not for everyone. Don't buy it until you've gotten to experience it first hand. I am more than happy with my 75a in my daily driver. Then again, riding around in the back of Bradleys and Blackhawks didn't give me much trouble, either. My butt dyno and tailbone section are probably permanently desensitized LOL.
