It was recommended that I get these to reduce engine movement /knock that I now have because of the front control arm bushings making things stiffer and not sharing some of the play.

What are all of the benefits to replacement engine bushings? Is there increased vibration? Do they/can they make them in different "softness" levels?

 

I have the NM engineering insert and it just feel so much better. You lose power from the motor torquing so why not reduce that

 

Do you feel that there's noticeably more vibration with the NM inserts?

 

I have it on my car and I do notice a different when changing gears. Less rocking back and forth. It's a great gain for the amount of cash you're going to dish out.

 

There is a little more vibration but not a lot it really isn't that noticable but I have had inserts on other cars so I knew what to look for. You might not even notice it. Plus its not like your teeth are going to rattle out of your head.
