Motor mounts - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So I have a stg3 cam. The engine shakes a lot and I'm getting worried that my mount is detiorating fast or will break. I'm thinking of putting in solid mounts, or close to solid as I can. Will my car end up shaking more with the motor being solid to the chassis?
I don't daily it, it's becoming more of a weekend racer more and more as the years progress so noise and idle vibrations aren't in my concern list.
What would all change with the harder mounts in terms of drivability?

Do any companies make solid mounts now? I know pfadt And prothane both have close to solid.

Hit me with your advice

Your car will shake more with solid mounts as there will be a more solid connection between the engine and frame. You'll get used to it and not notice it after a while. It didn't take me long to get used to my Pfadt mounts.

BMR, Pfadt, Detroit Speed and Prothane offer solid mounts. I don't know if Pfadt still does. My work computer won't let me go to their site.

I'm ok with whole car shaking (looks badass) which is kinda what I expected.
After a little more research it looks like bmr has a bushing swap From the poly to aluminum for a real solid mount. That's the only that I have seen.
I have also read that when stiffening up the motor mounts, its recommended to do the same with the trans mount. Looking for that now with minimal luck so far

Prothane engine mounts..works of art....for manual trans somebody makes a poly insert that apparently works but since I put in the Prothane, everything works perfect..including the 7k shifts!

Ive been using my stock M6 trans mount with no issues. This is the third engine it's been behind with all of them making over 1kwhp. If/when it dies, I'll put on a prothane.

I have the BMR Polyurethane motor mounts in my car. The car actually shakes less. You feel more of the engine harmonics but not in a bad way in my opinion. Installation was fairly easy.

You have mounts...Plural, and get used to it from a old motorhead its part of the appeal of being cammed, and just as prevalent on any other cammed good car your engine mounts actually have fluid in them in the Camaro and are pretty sturdy.
