It does what it says. But all the vibration of the engine can't be absorbed by the motor mounts and it enters the cab. Great for track cars but not so good for street cars.

Did what they said, however, my hood rattles at idle. Starting from a stop makes a very loud shake of the engine. The vibrations at idle wouldn't be so bad except the hood rattle is so loud it sounds like there is something wrong with my engine. Very embarrassing.

Initially I was quite pleased with the product. Id say it took a total of 5 hours to install both inserts. The product definitely works! Shifting from 1-2 was definitely smoother and also when downshifting (previously there was a bit of a jerk that could be attributed to the engine rocking) The reason why I have decided to remove the product is that it has caused all sorts of rattles and vibrations. A vibration can be felt at idle that is not audible, which is the one I could live with. However, when acclerating in first gear (1-2k rpm) I have a buzzing/rattling noise, which is hella annoying. Also the engine sounds coarser with the inserts. Im going give the Ignalls torque damper a try to see if the same effect can be achieved without the noise and vibrations.

Theres no doubt these energy suspension motor mounts do exactly what there supposed to by diminishing wheel hop and controlling torque, however, whether or not the vibrations that come along with it are worth it is up to you. I do not recommend these motor mount inserts for daily driven cars. The vibration is very annoying and even embarrasing when others are riding with you.
