Does anyone have the CPE lower engine mount installed on a 3.0l? If so, how bad is the vibration increase. Where would the vibration increase fall between an OEM mount and a Urathane mount. I use my car as an every day driver and don't want too much increase in vibration. I have had urathane mounts before and could not stand how much increase there was in vibrations. If CPE is too much increase is there another one someone would suggest other than OEM?

If you don't want any vibrations, get the AWR or StreetUnit in a lower durometer.

You'll still get more in cabin vibration with the lower durometer SU mount compared to the stock mount, trust me. But it's nothing to worry about, either....the increased vibrations are only noticible if you're really trying to think about it.

+1 to the above posts. You have to pay a bit to play a bit. The CPe mount wont shake your lug nuts loose. But you do feel it. Now when I got into the side engine mounts is when I noticed a definitive change in the characteristic of my 6 at idle.

Is that b/c the stock side mount is filled with liquid to reduce vibrations and the AWR one is just metal?

So it sounds like the order of options regarding vibration and stiffness for response are:

OEM (sloppy but low on vibrations)
StreetUnit (a little stiffer, but has a lower 62 durometer to address vibrations)
CPE (middle of the line durometer at 70, sounds like a noticeable vibration increase but not obnoxious)
AWR (urethane bushings, this will give the most rigid response, but a significant increase in vibration)

CPE hands down. The urethane transfers a lot more vibration into the cabin. I have the 70duro CPE wishbone, and a AWR 70duro urethane tranny mount, and I notice the AWR mount vibration, but the CPE is not even noticable, and wasnt so much even b4 the tranny mount.

Another thing you should consider is that the CP-E is made out of EPDM rubber, and this stuff is the best! It has the heat resistance and elasticity of rubber, with the hardness of urethane. Personally, I hate urethane mounts, since they can easily get dirty or dry, and can make popping and creaking noises. Urethane also has a different memory, so it can get distorted after awhile. Once that happens the noises will only get worse and you will have more movement. It also seems to be worse in the cold and rain.

I had wanted to get a bushing manufacturer to make EPDM bushing replacements for the AWR mounts and the suspension. Not much interest from the manufacturers, and it costs $700 for a mold.

Go with CP-E, you will not be disappointed.
