Yes, you are right we do disconnect the swaybar but it has nothing to do with leverage point along the length of the swaybar ends. It has to do with a thing called Preload not "bind" and we do it so the weights of the car will be more accurate as we adjust corner balance so the swaybars will not give a false reading. As we make this adjustment its extremely rare ride-height will remain constant from left to right side. As a result endlink lengths have to be varied to ensure no preload is placed on the bar.

Now, endlink length will effect handling as it changes suspension geometry but from side to side we are talking a very small amount that no one would ever notice. However, I will add that usually shorter swaybar endlink length will result in a higher resistance across the swaybar much like rod length inside a motor.

What we find on stock cars is no swaybar adjustment and no adjustable endlinks. That is fine as usually on flat ground when the car is settled there is very little to no preload on the bar. Now, if you add adjustment holes and run your bar on even settings this will stay pretty much the same. If you run in staggered holes your going to introduce alot of preload on the bar because the endlink lengths need to be different lengths to produce a no preload setting. Now, as you can imagine if you do this and take out the preload the closer hole is going to have a shorter endlink setting and the further hole will have a longer endlink setting. I am not sure about the 370Z but 90% of the cars I have ever setup the closer hole on the swaybar to the suspension mount point is almost always the harder setting on the bar. So this would only compound your problem of uneven leverage across the bar given not as much.

However, if that is not the case the swaybar endlink length might play in your favor but I must say that the leverage change from swaybar endlink is nothing compared to the leverage change of the length of the swaybar leverage arm.

Overall, I still think its a bad idea to run a staggered swaybar setting as all physics that I can account for tell me its not going to give equal results from right to left side.
