I watched a video of my dyno run for engine movement and there was virtually none!! it was solid as a rock. so they are doing their job in that respect.

Couple quick questions though. Is the diameter of the bolt running through the urethane crucial? I see you guys using 3/8". Is that the largest diameter that will fit? Why not Keep things metric with an M10, or M12 bolt?

so basically, a 10mm bolt would probably work just fine. I will probably switch mine out sometime just for consistency.

ok, i drove it to the club and back..it was very interesting, there was some added vibration, but not what I was expecting...it was a very low tone vibration,and only prominent in the lower rpm range(1-2) during slow acceleration....however, the funny thing is that the exhaust sound is now a bit heavier, sounds more like a real race car lol (heheh)...
i really like how it tightened it up, at idle I used to be ableto watch the motor move around in the engine bay, now, solid as a rock, and before I could move the engine back and forth with my weight, now when i pull on the engine the entire car shifts back and forth...got to love that
...so far I like it...and assuming soem of the vibration will tame itself over time, then it is a great mod.
one thing I was bummed out about was that I still have the slop in the drivetrain (on-off throttle or shift in forward/backward momentum), although reduced a bit from the new mounts. I at least I know that its not the motor mounts, i mean, now my engine play is almost nill, so maybe its the ppf (power plant frame) or the diff bushings...fortunetly I have some unobtainium bushings sitting in a box :-)
hey ISUposs, what kinda noise did you notice when you installed your diff bushings?

I just installed solid diff mounts when I put my 4.777 final/cusco diff in the 7.
Don't know how to explain it, but the car feels "solid". However, I also installed a 5 pt roll bar and a rear subframe brace along with the solid diff mounts so that's where the rigid feel of the car maybe coming from.

update
here is an update on the mounts...
Vibration notes:
I don't even notice the minimal vibration that was there in the begining, if I pay attention to it I can still detect some, but it has smoothed out a bit.
Stability notes:
I am real happy with how stable they keep the engine, it used to move a lot even at idle, and not, dosnt move at all. I used to be able to pull the engine back and forth with my arms, now, it sways the entire car when i try.
Is the job really as easy as it sounds?
Basically yes, remove and disasemble the old mount, cut the urethane to proper size, drill ahole in its center, reassemble mounts, re0install (and add a 'waffer' on teh bottom if you want, as mentioned above in this thread)
A few sticky points:
The hardest part for me cutting the darn urethane, I ended up buying a small power table saw from homedepot, it did the job well, but was messy. Also, getting the motor/tranny up enough to get my socket/wrench between the mounts and subframe was a bit tricky. The rest was easy and basic stuff, just follow the details higher up this thread and ur good to go.
I have plenty of pics a few post above this one.
A BIG thanks to ISUposs (Ryan) for pioneering this mod!!!

I went with the "sandwich" styled setup to try to minimize the vibration. It worked pretty well. It cleaned up the slop in my shifter that I was seeing from a broken mount (driver's side? I don't remember).
Anyhow, I autocrossed the car twice and put it through several spirited launches with no issues. it was kindo of ghetto, but it worked. Total cost was around $75 and like Damian said, the trickiest part was cutting the urethane.

You guys haven't developed oil leaks or anything since this mod have you?

It's No different from the stock mounts (because they essentially are the stock mounts). RTV the crap out of the bolts when you put them back in and you should be fine.

I went hunting in the junk yard just looking at different mounts. I saw a few different ones which looked as if they would work well. I considered the application and design and settled on Jag XJ6. I found a new pair on Ebay for around 30 dollars. I removed the bonded driver side mount and drilled a hole etc. I found a 1/4 inch spacer to raise up the mount close to the factory height etc. I Have had them in for a year now and they work perfect. I considered the load they were designed to carry and felt they would be able to handle 300 hp made the Mazda way with no problem. I even fitted the stainless steel cage around the mounts as well. I could have perched new ones but theres no way any mount is worth the money being charged by the suppliers. I also plain to make some other parts as well.

Sorry to bring this back from the dead, but in need of some help.
One of my mount arms, isnt flat like Damians. I can only guess i have an older model. It has that metal buldge on the end that holds the actual mount material (solid, wood, eurathane, hockey puck etc). I am about to install solid mounts onto the arms and that huge buldge gets in the way.
Do I just cut it off so that its flat? Its kinda hard to tell from all the posts ive read from searching whether or not that buldge is cut off or not.
Thanks
