Is this not odd to anyone else that COBB's bushing holes are oversized? Doesnt seem to make for a good fit.

Nice vid only thing they forgot was to Torque the engine mount bolts to the Ford Spec (Torque : 70 Nm or about 50 Ft lbs)

Well it should never corrode and bowjam up

True. But, its much looser spec than the OEM unit.

Also, I didnt notice any extra vibration at idle as others have. Nice and smooth w/ firmer shifts.

That's interesting because Cobb did not specify. They do for the Focus, but did not for Fiesta.

I will add that to the next version. I used the standard Ford "oomph and a half" torque spec because it wasn't specified in my directions.

@moshaholic: Do you have an exhaust already?

Just curious what the variable here might be with your car.

No exhaust yet (been waiting on a cp-e downpipe for two weeks)

Im not a drag launcher and perhaps my other mounts are in better shape than some others on here. Nor did I have the engine hitting my firewall.

for me the mod is for more positive shifts and better power application out of corners.

Glad to hear you're not getting the vibration mosh. I'll have to check it out whenever I see your car in person.

Installed mine today. I have a little cut on my cheek from the stock mount falling out and hitting me in the face lol.

My insert arrived today after just 2 days of sending the message that one wasn't included with my mount, amazing service from COBB as usual. Just threw it on and is it ever easier the second time haha. Took all of 10 minutes and jacking up only the drivers side front wheel. So much easier than other cars I've had. Couldn't be happier!

Gave her a nice little 1st-2nd WOT pull earlier. Grips much better and the annoying knock is gone. Now when I shift to second, all you hear is tires chirping haha

First time I heard the engine hitting the firewall, I thought I'd really damaged something. I'm going to install my Cobb RMM (engine isolation bushing) tomorrow. Can't wait.

I plan to get one but how many have had missing parts?

Pretty sure it was just the first few that were sold missing the insert. I bought mine minutes after they were available. COBB was aware when I sent them the message so any further should have it.

I'm quite curious about the engine hitting the firewalls. I've done repeated drag launches already and have never heard of this banging against something... Does this issue only occur to USDM model? Any euro model can confirm?

Edit: I've also noticed that I don't get wheel hop either... Maybe my mount is stiff enough already?
