Urethene motor mounts
#2
A service guy at my mazda dealership has them on his Protege sedan, and he recommended to not get them. I took a look at them with the car on, and it it makes the front bumper shake(vibrate). And on top of it a piece of it broke off! but maybe thats just his car

I can only think that the top part of the urethane broke off if he overtightened the bolt, as otherwise it should not happen. Anyways, the edges do nothing anyways, its the urethane in the center portion that do all the work.

but see, all you are doing is transfering the vibration from the motor which is built to withstand it, to the rest of the car. Now I know the iron blcok is more suited to withstand the shake rattle and roll than the plastic parts in the rest of the car.

When you rev your engine, it "leans" or "flexes" due to the change in RPM. This is more apparent when looking at the engine from the side of the car (i.e. looking at the pulleys). Have a friend sit in the car and rev it up from idle and you'll notice the block sort of tip toward the firewall. Urethane mounts stiffen up the engine in relation to the frame so that the engine flex doesn't occur relative to the PPF and the frame of the vehicle. This will reduce wheelhop when the tires are spinning and generally shorten engine response time. As a side effect, the natural vibration of the engine is no longer isolated from the rest of the car.

isn't that what i said?? by "stiffining" the engine mounts you are not allowing the engine to lean or move as freely and will transfer the vibration to the rest of the car. This is in fact the reason the engine is mounted with a certain degree of play, otherwise the car ride would be too rough and would prolly make holding a cup of coffee in the cup holder rather interesting. Although-i can see the theraputic value of a full body massage.

to put it simply the technology of urethane mounts is basically for racing/pretty spirited driving and drivers that will accept the consequences for every little detail that will make the car faster, handle better, etc. it wasn't made for everyday "hold your cup of joe while you go to work kinda thing" that's why they use rubber and liquid filled motor mounts from the factory. hell, i've seen in japan another new technology of the various crazy ideas they have is a shock absorber type dampner that attaches one side to the engine and the other to the chassis.

I hate my motor mounts. That is the first mod I wanted to do to my car. The sloppiness, combined with the nonlinear throttle (the computer "blips" the throttle when you push on the gas, fooling you into thinking you have more power than you really do), makes it hell in first gear in a parking lot. Anyone seen any hard rubber motor mounts? They make 'em for VW's, as a compromise between pitifully-floppy rubber and shake-your-fillings-out urethane. Hm, maybe Mazdas aren't cool enough yet.
