Default Anyone using urethane motor mounts?

Curious to see if anyone is using the following for motor mount replacement.

https://www.corvettecentral.com/c4-8...luminum-304930

Didn?t see too much on this for discussion outside of an old thread on solid mounts, which I do not want.

You might give Marc Haibeck a call to see what he is recommending for motor mounts. I am sure he and Bob install a fair number. --Bob

I bought & installed a set of Polyurethane motor mounts from another brand. I hated them!
They were stiff and made every part of the interior rattle & buzz with vibrations. Itwas terrible.
I had stock style mounts installed & everything is back to being good now.

I would only consider it for a race car. Thanks for sharing as that is what I imagined they would be like.

I am running urethane mounts on mine. I was hesitant because of some of the stories I heard but wanted the durability next to the Worx headers. This is the truth, it rides as good or better than my other cars with oem mounts. There is zero harshness zero vibration. I would install them again in a minute.

That is good to hear. Which brand?
