I am doing something I normally don't do and that is considering keeping a stock style part on my car. I need a new tranny mount when I put my tranny back in. I was originally going to upgrade to a polyurethane mount but now I'm not so sure. I did a search and found that many of you end up with more road noise and vibration as a result of the switch. This car is mostly put together as a rolling stereo system and will probably never see much over 350 HP. I would hate to gain a big vibration in the cab of the car that would get in the way of hearing my system at low volume levels. So with that in mind is the poly mount worth it or should I just stick with a brand new rubber mount?

 

the polly mount is not that bad. I guess my wife might notice a differance but, I sure didn't the only thing I noticed was the poly mount stays in one peice. I even put on the poly toruqe arm mount.
