First of the toe links have been replaced with adjustable to links, so that isn't the problem.

rear suspension is made up of:
T2 rear end and CV shafts (car is a 90 GTU)
KYB AGX
Full urethane bushing kit
mazda comp diff mount
pinion snubber
solid plastic rear diff mounts
eibach pro kit springs
strut tower bar

pretty much the only thing I haven't done is the rear steer eliminator.

everything is properly installed, nothing is loose

car aligned out fine

When I go over light small bumps there is a clicking sound, real low volume not loud at all.

Sometimes during a burnout/lauch there is a real loud hammer sound like hitting the floor board with a ball peen hammer, I think this might be the diff bouncing off the pinion snubber (in which case its probably not an issue) also likley unrelated but I though I would mention it.

I have had the car on a lift, suspension loaded and unloaded pushing pulling hammering on parts I can't simulate the sound.

Any ideas???

I had a similar issue, turns out that one of the muffler's hanger was loose (one of the sides).

Did you assemble the strut tower mounts properly? Double checked?

Yep one at a time with the help of the fsm.

How much camber are you taking out with the adjustables?

Might be binding the outer bushing of the rear control arms.

I only had 1.5 degree's neg adjusted back to factory spec primarily for street driving/drag racing.

My muffler hangers all look good and I have a flex joint in the down pipe, I don't think its that.

even though your muffle hangers look good, i have found that the muffler can bounce up and hit the rear sway bar, check the clearance b/t those
