I was curious if anyone has any first hand experience with Polyurethane engine and tranny mounts, and also engine torque dampers. Mainly i was wanting to know if these things make a big difference and are worth the money. I've been through 3 pairs of regular engine/tranny mounts over the years. and does the torque brace eliminate the "shudder" feel i get from accelerating? Thanks.

 

I've never gotten a shudder from accelerating. I think you may have another problem

 

im speaking from experience with my 88 z24 caviler, i had a shudder that was due to a broken engine mount during acceleration. i first replaced them with stock mounts but broke them a year later so i replaced all the mounts with poly about 5 years ago and love the mounts no probs worth every penny. i have solid mounts in my supra, for 2 years now, and just bought a set of solid for the fc.

 

i also put a torque link (a solid link not a damper) in the z24 about 2 1/2 years ago and it made a big difference. i have a friend with a 350z and he got a torque link and said the same, that it made a huge difference, he has stock mounts so did even more for him. and they are cheep at summitracing.com

 

I would do one or the other but both is a overkill since they basically do the same thing.

Good condition stock rubber motor mounts w/ an engine torque brace and good diff mounts provides a nice solid drivetrain that decreases excessive movement w/o adding any NVH

Poly motor mounts accomplishes the same thing as the engine torque brace but presents the risk of some NVH.

I've had both.

 

Polyurethane mounts are the best and are preffered over regular stock rubber mounts any day.
