Well I ordered a plethora of bushings on Black Friday. UMI Motor Mounts, Revshift Cradle Bushings, Transmission Block, Trailing Arm Bushings, and Differential Bushing. Did the motor mounts and transmission block this morning. Total it took about 5 hours because they didn't state in the instructions that you had to remove the starter (or AC compressor) in order to get the pass side bolt in.
Overall impression; F-in great!!! Whoever complains about vibrations from these mounts must have a sensitive ******* or something lol. The power delivery is alot smoother, and it definitely feels more connected to the chassis. I still get a slight shudder from turning the car off (still have the dual mass flywheel) but overall its definitely worth the time. I'll be doing the trailing arm bushings, cradle bushings, and differential bushing in the near future (preferably before the holidays). Sorry no pictures this time, but I'll definitely remember to take some for at least the cradle bushings.

Right on! Did you drop the exhaust to do the transmission block?
I just did my Revshift motor mounts today, I got them all in without removing the AC compressor or the starter, did you leave the dipstick attached? The driver's side mount was by far the harder one for me ...
I agree about the vibrations.... or lack thereof. It purrs like a kitten now, totally removed all the vibes I had with the stock (and disintegrated) mounts.

Some of the people that are worried about vibes have an aftermarket cam. You got one?
I have the umi mounts and they are great, no real intrusive vibes but im still stock in terms of a cam.

I didn't drop the exhaust for the trans block (magnaflow x pipe) but it did fight me for a couple minutes. When in doubt, a 36"+ prybar usually solves it.
Cam is still stock for right now. I'll be pulling the ROSE cam out of the impala, and throwung in the V in the near future.

I didn't have to remove the starter or the AC compressor to put the mounts in for the P-Side bolt. You just have to have the cross bolt installed before mounting to the block.
I think the level of vibrations you notice depends on what you are use to driving. I noticed them when i put my UMI mounts in (pre and post LS7 flywheel), but they are not really objectionable for a performance car (and in the passenger seat I don't notice them at all)

This probably goes without saying, but the driver is constantly connected to the drivetrain of the car in at least three ways that the passenger is not (four when you've got your foot on the clutch).
I suggest, on a going-forward basis, that we identify the location of the vibration as well as its magnitude. Unless perceptible vibration is being transmitted through the frame of the car, the passenger won't feel it.
