Rmm? Softest with no bang?

Hate to beat a dead horse. Have a FiST on order. I really want the Rmm with minimal nvh affects but will not allow the engine to bang the firewall on hard shifts. No too concerned about wheel hop. Anyone have the breedt with the 40 durometer bushings.

I have a Cobb too - there is some minor NVH at idle (a little more with the with the a/c on) but it's nothing crazy

I have the Mountune mount. I went with it because between it and the Cobb, they are considered the softest of all available RMMs. In the modbargains blog (read it here), they mention that the Mountune is slightly softer. I made my decision based on that. I only remember its there when the A/C is on, but not always. I'm happy with it mostly. Be warned though, there's a good chance it'll squeak when driving slow I'm not the only one that's had this happen.

It isn't annoying or anything you can't hear it with the radio on so I just kind of ignore it.

I'm 700 miles into my Cobb and hardly notice it. Still a bit with the a/c on but strangely enough, if a blip the throttle it almost goes away. I chose it because it is a direct replacement. The Mountune YouTube video says you have to do a slight bit of drilling. I didn't want that.

The drilling seems to be completely unnecessary. It's only done to push out that metal plate attached onto the oem motor mount.
COBB's method instead is to just remove the oem motor mount along with the metal plate attached. Then hammer it off.

Mountune and COBB's mounts are almost identical physically, so they can be installed using the same method.

Mountune here really mellow. As stated above no drilling required. One decent hit with the hammer and the brace is removed from the OE.

One thing to note all RMM will be stiffer for the first say 1000 miles. Some will need a little longer but they all smooth out nicely. Rather good investment as I was bottoming out the OE one regularly.

I've had Cobb and Mountune, and the Mountune produced less NVH in my opinion. There's also the insert, which I haven't read too much on: http://www.modbargains.com/ford-fiesta-st-rear-motor-mount-kit-powerflex.htm
I have the big and small bush. They work a charm, but it can be a real pain to remove the original bushes. I had to remove most of the old rubber and cut the metal rings with a hacksaw to extract them without a hydraulic press.

If I did not just drop over $500 on HID lights and Led Fogs and the Fswerks short shift kit. I would of ordered the COBB this weekend as well. I am going to ordering the COBB in the next few weeks since I do not want to spend any more money on the car this week. But I am glad to hear everyone likes the COBB, seems the best for the price and fitment.

Found this online...

Would be worried as to how long this would last and if I ever wanted to go back to stock oem, would have a problem.

Have had cars with this hold up for long time.......why would you need to change mount back to stock? And even if did stock mounts sell for next to nothing.
