Corksport motor mount inserts installed

I installed the Corksport motor mount inserts yesterday with some help from my neighbor (need another body to rotate the engine so the mount can go back in). Looking at these pieces, I think that filling in the gap in the rubber bushing may be only the secondary reason these things work. The factory mount is higher in the center than on the edges. This means that it can rock up and down easily when the engine tries to rotate. The inserts, in addition to filling in the gaps, change the profile to more of a hockey puck, the same thickness all the way across. This profile is much more resistant to rocking than the factory version.
The effect is very noticeable. It adds nothing unpleasant to the experience of driving the car.
When starting the car, I now feel it when the engine catches, and when starting out from completely stopped, things are a little different, but not in a bad way. You really notice how instantaneously the car starts moving under those conditions.
Without the slop, the tires don't do their "squirming" when I stomp on the gas so the car just takes off. Oddly enough, logically I know that this has to translate to better acceleration, but psychologically, losing the tire spin due to the engine motion breaking traction makes the car feel less powerful.
So much of our fun is all in our heads, I guess.
Summary, not too hard a swap and well worth the small change and time it took.
 
i know i saw a how-to on this forum somewhere but i forgot where.. can someone please link it.. i got my mounts in like 3 months ago and still havent put them in yet.
 
I installed my MM inserts this past weekend. It was pretty easy to get the mount out, but once you add the inserts, it sure does make it tough to get the mount squeezed back in there. I really like how the car starts with these inserts.

One thing though, I need to get used to the slight increase in vibrations that you feel when you take off and the car is cold. Once the car warms up, the vibrations are minuscule.

I recommend having a friend around when it is time to put the mount back in.
I did this on jackstands in my driveway and getting leverage to rock the motor to where I could slip the mount in place was a bear. My neighbor crawled under with me and he pulled the motor into position with a prybar while I put the mount in place. The increased thickness of the mount makes it a challenge to get back in.
Looking at the pictures of the dogbone mount, and considering the new shape of the factory mount after the inserts are put in, I don't see that the dogbone would be much if any of an improvement over the stock mount with the inserts. Maybe with the extra hard material, but that small mount area looks like it would rock up and down pretty easily, whereas the stock one ends up with a much larger surface area, which should fight rocking even better.
 
the easy way around the difficult squeeze when putting the mount back in is to unbolt the mount that the rear mount is mounted to. this mount is the one that is bolted to the rear mount using that horizontal bolt. it is held in place by 3 bolts, and all you have to do is unbolt 2 of these 3 bolts and loosen the 3rd so that you can swing this around. after you do this, it's easy as pie to fit the mount back in...:D

I saw those bolts and thought about it but I didn't know the torque specs on those bolts so I decided against it.

ya, i just tightened them to the same torque (80 ft-lbs) as i did the other ones. i can't guarantee that's the proper spec, but that's an educated guess that i was willing to live with.

here's a pic of the additional bolts that i loosened (compliments of KaiserSoze from the other forums):

Ya at 35 bucks thats not bad. My only concer is that the stock bushing is still in there, possibly wearing over time?
