I've seen different combo's used, what is the consensus?

My vote is for solid all the way around, I have sport engine and solid tranny.

solid @ engine bar to chassis, chevy @ engine bar to motor.
Sport @ transaxle.

Does a decent job of cutting out vibrations, yet controls movements really well.

Have run just over 500HP on R-compounds this way w/ no mount related issues (dont ask about trannys....)

We need a tie-breaker...

Do you want the trani to move? Do you want the chassis to move? Do you want the engine to move?

I have no experience..

I have 3 sets of mounts holding my engine and transmission in. I use the renegade cross-member and Chevy mounts on the engine along with Cadillac body mounts on each end of the cross-member. The transmission has 911 mounts. Works great and really helps with engine vibration.

I assumed most have the rubber chevy engine mounts (correct me if that is not the case.)

One thread mentioned those engine-to-cross-member mounts are enough to isolate the engine vibration and you could improve shifting with solid elsewhere..

I agree, thats what I run, feels great!
