i have over 100,000 miles(i made the first one for my 2000 SSEi) on my solid mount with NO PROBLEMS .
take a look at this post
i did not have to jack my mortor/tranny , just take out the old mount and put in the new one.The distance between the bottom of the motor mount bracket and the top side of the cross member on my car is 3 5/8 inches. When you step on the gas that front motor mount trys to tear itself in half. You can use the hockey pucks, or anything that can take up that space. I would suggest a 2 1/2" or 3" hole saw and cut a couple of disks out of the sidewall of an old tire, to put on top and bottom of the hockey pucks. The only weight on the spacer is when the motor is at rest. There is no weight on it when you are under power. When you are under power the engine torques backwards trying to tear the bolt in half. I suggest the use of the tire sidewalls so you can tighten the bolt down good and compressed on the hockey pucks to keep them from vibrating. Tell us how it all works out and if you like it or not. I do not notice any vibration but I have had mine on for four plus years.
