Got these yesterday, installed them this evening and very pleased. It's a very simple install as the inserts fit perfectly on both sides of the mount. The install itself took about 35-40 minutes.

At idle the car does have some slight vibration with the AC on, but it's nothing that concerns me. With the AC off you would barely know it was there. Mind you I'm coming from messing with dsm's for many years with full poly mounts. While driving the vibration is non-existent IMO even with the AC on. The big change is how much more the car feels connected when shifting. That softness/floating feeling when shifting while you're driving normally is gone, making shifting feeling much more crisp. Full throttle shifting also has a more crisp feeling. The inserts themselves feel squishy but make a huge difference when inside the mount.

Just giving my feedback on this product I case anyone else has been contemplating it.

Overall very happy with my purchase, and would recommend.

I also installed some a few weeks ago and I’m also pleasantly surprised how good it is. A nice cheaper alternative to a rear mount upgrade. I also would highly recommend this to people, especially if you’re on a budget.

Thinking about getting it. Before I do I got a quick question. Are they easy to remove if I ever want to go back stock?

Yes, it's just 2 half's that slide into the stock mount on either side. I was just thinking and if the vibration of having both sides in bugs to, maybe you can use just one side to make it more comfortable and still have the benefit of a slightly stiffer mount.

Just installed my FK8 RMM with Perrin Inserts on my Si and it feels amazing! Vibrations is very very subtle and barely feel it as it only happens in 1st gear take off and reverse. Had AC on to test the vibrations too and was the same as with it off which IMO is nothing.

I just installed these today. The vibration at idle is more than I would like. Has anyone tried using half of the kit to see if the vibration was lessened? (Perrin, any comments on that idea?) Aside from idle, I like it. I will be using the car for audio demos for my shop, so I can't really have that amount of vibration and noise at idle.
(I also installed the solid shifter bushing today too, I like the extra bit of precision it adds to the shifter feel)

I tried with AC and no AC and the AC on makes the vibrations. It's Florida, so no AC isn't an option.
