How does the ACD reflash and rear diff effect spring rates?

Another bit i want to add. I was also from the camp that prefer larger spring rates in the rear, which is contrary to all motorsports level suspension enginering.
Then i started playing with my rake and jesus christ. 6mm more rake made the difference between a balanced setup at 8/9 spring rates and rear sway at soft, to a setup that is wildly uncontrollable in oversteer. I moved my rear sway to full soft and reduced rake to control it a bit better
This gives me a hunch that perhaps a spring choice based on corner weights would be best, using rake to manipulate your roll couple and control load transfer front/rear. This deserves serious experimentation.

I'd be willing to bet its more of a bushing issue. I've felt shudders before on my BMW during braking and some turns and it was because the front control arm bushings were beyond shot. The control arms were literally banging inside of its worn out bushing.
What do you have for aftermarket bushings? Engine? Transmission? driveshaft? diff? control arms?
