Start ridiculously soft in the rear on purpose, run a session, add 1-2 clicks , run a session, It will be pretty obvious when you need to undo a click or 2. Write it all down!
unfortunately this doesn't work for the Z (at least was in my case). I tried it and it was terrible. Though some told me not to but I still did it as it's how the "RWD" setup works (stiff front and soft rear). Car wasn't turning at all, ABS was pissed off, really unnatural feeling and rear end/tire was going to a point and snapping oversteer that was harder to control.. Z is a weird car ..

Came home and changed to almost 7-8/10 stiff rear and lets say 5/10 stiff front, car was superb. Turning really well, very balanced and brake felt very nice. I'll post here two videos: before adjustment (driven by a friend of mine who's a very good autoxer. You'll see him struggling too ) and then later with the change in setting w/me driving

Before setting change (stiff front/soft rear)
