I would take out those spacers since the subframe isn't raised. They might not be the whole issue but they are still throwing off the driveline angle from what I am thinking.

[YoungCR]

I'd check the u joints to see if they move freely. Could the engine/trans mounts be stiff enough to cause you to feel more vibrations?

[ClassE]

I'm thinking that's exactly the issue Chris. The vibrations were there before - but ancient OEM motor and trans mounts didn't transfer the feeling into the car. Once I went solid mounts - all those vibrations come to light.

Ill trade you a set of regular subframe bushings for those riser bushings. made from uhmw as well.

I have zero intentions of dropping the subframe again soon unless something breaks and I need to remove it.

I decided last weekend I will be going with air next winter, roads are just too crappy to be low static.

Wheel bearing time - and giubo/CSB time!

Which one do I pick?

"Bolt-On" ... Not ... "Swap"

Your subframe is lowered and your diff is lowered quite a bit. That is bad news bears for your U joints and driveline angle. 
Even the lowered subframe is not great
It's not a CV joint so it will throw some serious vibes if it is outside of its allowable range. 
I still have the back half of a good shaft if you need it.

I think the current plan is to swap the CSB and Giubo onto the original driveshaft - and bring it in to be balanced. If it balances out good it'll go back in... If not - I'll have to address then.

[GunMetalGrey]

If your U joints are shot you will still get some clunking back there, the joints shouldn't have any play.

[DrLeadFoot]

No play and there shouldn't be a lot 'sticky' spots when you move the joint around.

[ClassE]

Once removed - I couldn't find any "slop" in the u-joint at all. Moved freely and didn't have sticky spots.

[DrLeadFoot]

That's a good sign

Didn't get as much done this morning as I had hoped - but overall got stuff done! New rear bearings are in, rear axles are in - gonna eat some lunch then reassemble rear brakes and move to radiator swap I think.

Give er hell!
