My only experience is with the cobb rmm and I torqued to spec via their description and never had rattle.
CFM RMM - worth it for $120?
so many of you say the RMM is great, but many also say it vibrates like hell... this is a daily driver, so recommend?

bump for more input
Mountune's was only a bit more for black fri, I think about $135, and I haven't seen anyone report a lot of vibration. I can confirm, along w/ a front traction bar, car launches great w/ a minimal seat massage.
NVH is highly subjective. One person's "slight increase in vibration," is another person's hell. I have the CPe Stage 2 RMM. Everyone said, it's mild. F that. I'm pushing 40, I should have known better. You never get used to it, it's there, you will feel it in lower revs, or coming off from a stop. But only from a stop, not during driving.
Are the normal RMM's better (i.e. stage 1 esque? Probably. They are only replacing 1 bushing, not two.
Mountune's seems to be highly rated. But again, NVH is highly subjective... IF I had to do it over, I'd probably go that route, and sell the CPe and break even.

Not necessarily true. I have the steeda 1 piece mount with the "street" set of bushings installed. I rode in my friends with the cpe two piece mount and it almost felt like his had less vibrations. Also could be because I was in the passenger seat vs. the driver seat, but none the less. They both had vibrations. I also removed mine after installation, and re-torqued everything to spec just to make sure I installed it properly, and it didnt really change at all. I've learned to get used to it. I may switch to the "Race" bushings in the future because if im going to get the vibrations, i might as well get all the benefits of the motor not moving around on me and less wheel hop.NVH is highly subjective.

If you want to get rid of your cp-e, I'll swap with ya =)
I started with the CPE and like mitch808, it rattled quite a bit. People say that is "settles in", but I think it is that you just get used to it. I sold the CPE and went to the CFM and couldn't be happier. It is my daily so I wanted better performance than the stock one but wanted to keep all my fillings.
Trying to decide between the CFM and the Mountune myself.
I like the CFM myself; I noticed no added vibs after installing it, but I was replacing the e-Focus mount and already had both Turbo Tech uppers, which shake pretty hard at low revs.Trying to decide between the CFM and the Mountune myself.

You just tried to argue with me using subjective analysis, and an uncalibrated butt dyno.

I have the cobb rmm. I think its 80a urathane and when i first installed it i got the super vibes but after 5k miles it feels stock
I had the e-focus RMM only and switched to the CFM with all 4 pins. Noticed a little bit more vibes initially. It wasn't bad IMO at all (subjective). After a while, it broke in a bit and I don't notice any vibes at all. Considering buying/putting in more pins. It's worth it IMO.so many of you say the RMM is great, but many also say it vibrates like hell... this is a daily driver, so recommend?

When they break in and the vibes start going away, do the symptoms we're trying to correct with a stiffer RMM start coming back?I had the e-focus RMM only and switched to the CFM with all 4 pins.

No...."shift bang" is eliminated. Feels more "planted" as well.When they break in and the vibes start going away, do the symptoms we're trying to correct with a stiffer RMM start coming back?
I have the boomba racing rmm n I really like it

The absolute, hands down, single best mod I ever did to my '14 FoST was to reinstall the stock RMM. The aftermarket one drove me fu*&@#ing banannas. Yeah, you could get around the worst of the vibration by keeping the rpms high before engaging the clutch, but it was annoying. If the RMM actually completely *solved* the occasional wheel hop problem, then maybe it would be livable, but my experience was that it was all downside and no upside. I don't want to name the brand, but it wasn't the one you are asking about.
Mountune is the way to go. I honestly hardly feel vibrations. Even when first installed, the vibrations were nothing. There are some vibrations when you have the AC on at full blast and idling but it's very little.
