Wheel hop explained, and YES it is mount upgrade related. All? No, but a good part of it:
How Do Energy Suspension Motor Mount Inserts Reduce Wheel Hop?
Energy Suspension Motor Mount Inserts are best known for their ability to reduce wheel hop and allow high performance vehicles to put more power into propelling the car forward. Energy Suspension Motor Mount Inserts operate with the same principles as Solid Motor Mounts. Many ultra high performance vehicles use solid motor mounts because they allow for very little motor movement. Because the motor is held firmly in place, there is no bouncing of the motor assembly. This allows the entire driveline assembly to maintain a solid geometry, reducing the excess movement caused by the otherwise violent release of power.

|Von551||a stiffer E-Focus rmm will help. this video is a great visual. http://www.youtube.com/watch?v=Sr6ssEdlAl4|

|Bogey||I could see it(RMM) making a difference maybe slightly in the noise that we all hate.|

WHEEL HOP IS 100% SUSPENSION. PLEASE TAKE THIS FROM AN ASE CERTIFIED TECHNICIAN!
If you don't trust me... go put the mount on and then put the GoPro facing the wheels. They are still hopping. Then put the factory mount back on and install a "GOOD" quality suspension SYSTEM (not just springs) and the wheel hop will be almost gone. There are differences in all cars, tires, pavement, and drivers, so one cannot say wheel hop will be completely gone.
With the wheel hop gone and the tires not hopping your car can and will still break under hard driving. Please refer to my car at FocusFest... I twisted the axle!
On a sarcastic note please refer to youtube for all you technical support!

Of course you're going to see engine movement with wheel hop on a fwd as they are directly connected to the hopping wheels. The problem is that you're trying to correlate the motor mount/engine movement as being a cause when you're actually seeing the after effects of the wheels having already broken loose. Had the tires not broken loose then the motor wouldn't have the ability to unwind from the torque.
I'm going to have to side with Mac on this. If you left the OEM mount installed but swapped your tires to full-slicks and had your suspension properly tuned, I highly doubt wheel hop would be an issue. More than likely all you would observe is your car getting traction and then your engine would bog due to the lack of power to break them loose.
I'm not saying that a RMM isn't part of an overall powertrain solution on a more purposefully-built racecar, but when I had my PS3's I couldn't experience wheel hop due to the inability of spinning the tires to start with. The only time my tires could come loose was if one was partially unloaded (in a turn) or if the ground was wet. I never had wheel-hop issues even on the OEM RMM.
And I have no idea why people keep bringing up RWD information as it isn't pertinent to a FWD setup at all. My Armada squats when I launch it but that is completely irrelevant to my Focus.

|mac.mogul||I'm not going to sit here and explain again why the engine mount has nothing to do with it.|

trans-axle wheel hop on a rwd is another thing because its the leaf springs that cause the hops
p.s. sorry for my terrible english skills

I have coilovers, and wide tires. The only time I get wheel hop is when I'm beating the crap out of the car. When I take the car to the track the alignment fixes the wheel hop. As in anything you have to give in one area to get in another. Do you want a car that wheel hops or one that is going to chew through tires a little faster? Do you want a car that is going to ride like your on pillows (factory height) or do you want one that is going to carve the canyons (coilovered with 2.75" drop and customer spring rates). The motor mount does nothing for wheel hop. All the rear motor mount does is when the wheels start to hop it keeps the engine from rotating when it is loaded and unloaded very quickly. The noises that most think is the car coming apart is the rear engine mount itself banging on the subframe. When the mount is replaced the engine does not move as much but the wheels will still hop under harsh driving... My thoughts "drive it like you stole it and then fix it when it breaks".
