Nismo engine mounts with Urethane Trans mount?

[sr20drft]

I was just wondering what you guys would recommend for mounts. I'm thinking of going with the Nismo engine mounts along with a Peak Performance polyeurethane transmission mount. Is this an ok combo, or should I go with polyeurethane engine mounts too?

What are the ups and downsides to polyeurethane/nismo hard rubber?

Rubber = Polyurethane. Stop being fooled with gimmicky words.

depends on what you want. if you don't want the engine to move at all, go polyurethane. of course this means the engine vibrations will transfer to the car/chassis instead of getting absorbed by the mounts. the nismo hard rubber (which is what they are, they're not considered/listed as polyurethane/urethane) is a compromise between the stock and poly (although metal mounts would be the extreme, i don't think anyone in their right mind would use em for daily driving.) your planned setup is ok.
