So I can wrap up this thread now that I got to really exercise the car on a day long 300mile excursion. Let me lead with this- I would do it again but earlier. Waiting didn't save any money and the car could have been like this for a few years now.
The car tracks flatter, turns in quicker, and doesn't waggle boosting off a corner in 2nd gear like it used to. Brake dive is better and so is squat under accel (although I don't have the power many of you do). I do wonder if the Tarrett bars are adding some thump into the cabin that rubber bushings would lessen. I may disconnect them next spring and take a ride just to see what part of the equation they are playing. I have them full soft in the front and mid-way in the rear to start with, and didn't learn anything on the street that would make me change them yet. I didn't push the car to where I experienced any understeer or oversteer in either case. Another interesting observation is how sound plays a role in feel. I had noise canceling headphones with me and when they are on, the car feels more civilized, more modern if you will. Take them off after a bit, and it seems like the harshness of the road imperfections grows. Of course it doesn't, but this is a very repeatable sensation.
Lastly, like many of these suspension updates, I can't say how much is just due to R&R-ing 26 year old parts and how much is the bushing and shock design. No doubt the car was never this firm- that's just math- but the feedback is much more direct. I can't wait for a track day!
Here's how she sits after the CB and alignment:
