Not trying to be negative, but try this test: W/the AC on, sit at a stop light for the usual 3-4 minutes at idle. Don't kick up the R's, just let it idle. Then see how the vibe is.
I had the 70D AWR in my NA for nearly 2 yrs and I couldn't take it anymore. It kicked on start up, which didn't bother me too much, but sitting at a SL in the hot summer with the AC on full blast, the vibe in the steering wheel, dash and rest of the car drove me nuts!!
I just installed my 75 duro CP-E mount this morning to replace the CorkSport inserts. This is far from my first rodeo with stiffer mounts, so I immediately kicked on the A/C to test the vibes at idle. I'm actually surprised with a mount this stiff that it didn't vibrate more than it did. You'll definitely feel it, especially in the steering wheel, but it's well within tolerable limits (this is my grocery getter/Home Depot car). It's a tad louder in the car under load with the vibes being transferred across the chassis, but the engine barely moves now and is that much better to drive.
