A few weeks ago I decided to go ahead and install the rear lower torque mount from the electric ford focus. Since we all share the same platform, but the electric motors have more torque, ford obviously beefed up the engine mount to handle the toruqe, so this is a nice "upgrade" to our stock mount. The biggest draw to this mount over simply buying an aftermarket mount, is that it costs well under half the price of any other mount and IT WORKS. These cost roughly 45 dollars in the USofA and roughly 65 here in canada (don't know why It's more but oh well). This mount is praised on the ST forums, and I can see why...
Ford Part No: CM5Z-6068-A
Here is a pic that compares the ST mount to the E-focus Mount (E focus is at the top)
And a video to show the difference in flex:
As you can see, even on the ST, the stock mount sucks and obv allows for the trans to slap around.
I'm sure a few people already know about this mod, but this is more to outline "What you should buy if you want a RMM, but are going to whine and complain if your car vibrates after you install one". THIS IS YOUR MOUNT. THIS IS WHAT YOU BUY. THIS WILL STIFFEN UP YOUR TRANS, QUICKEN UP YOUR SHIFTS, HELP WITH WHEEL HOP, AND NOT MAKE PENNIES DANCE IN YOUR CUPHOLDER. THIS IS YOUR MOMENT
