Motor mounting, solid vs transplate vs poly etc

[Slick]

Thanks for the input guys. How about some reasoning though? Why does a tranny need a rubber/poly mount? etc. I just got a ride in my friends TT camaro with solid everything and the only vibration was my head bouncing off the back of the seat when the boost kicked in ( god damn), and that thing is not tuned at all, he's never messed with an accell gen7 and it's ROUGH right now and that's the only vibration I was feeling, when it spit and sputtered. Is it just in how the engine is built?
