Could some of the instability under braking be caused by toe loss when the rear end is unloaded?

I'm unsure about those ride height numbers since I don't have a point of reference.

Rear toe out gain is also a possibility. If there is a considerable amount of rear-steering is built into the suspension design, rear would toe out during a hard braking. However, this is only at an autox; can you adjust your driving style to take advantage of it? I don't race my 370Z, but many years ago when I autoxed my '95 Eagle Talon TSi AWD, I gained a habit of trail braking because the car would rotate under hard-braking.

One other thing, if the instability was indeed due to the rear wheel steering, see if more toe in in the rear could be dialed in.
