What's the difference between those and engine mounts, since the poly roll resistors stop wheel hop right?


These are engine mounts. They are mounts where the rubber has been removed and replaced with a hard poly filling. The specific mounts discussed here are the front and rear transmission mount for a MTX. These cost wwwaaayyy less, are stronger and do not wear out. The poly-filled roll resistors do stop wheel hop. However, brand new regular engine mounts will stop will hop, but they will eventually wear out. Also, the poly-filled ones increase NVH, but you become used to it very quickly.



No, they are roll resistors and do just that, they resist the motors want to "roll" from front to back in the engine bay durring acceleration, decelearion, and prety much any time you're driving(cause of wheelhop=misaligned drivetraine). Engine mounts are again, just that, themy mount the engine i nthe car(located on the left and right side of the engine).

Even brand new roll resisotrs WILL NOT stop wheelhop because of the slop that is built into them for noise comfort.

Do they bolt off and on without having to support the engine or take anything off?


Yes, they do. There's only 3 bolts or nuts that need to be removed to swap each mount.



Front: 2 nuts, 1 thru bolt (15mm all)
Rear: 3 bolts, 1 thru bolt (15mm all)

You do not have to support the engine, but make sure it's properly aligned and positioned before tightening the thru-bolts or the NVH will get out of hand(speaking form a LOT of experience). With the engine propperly located there is little to no vibration, ask 99contourdriver, as he has been in both my cars which were equiped with my mounts. I suspect misalignment is the issue with most people who have any problem with the resulting NVH from my mounts.
