I have a fix for this and I will try to describe how I did it...
The ALC system has a sensor and its attached through a ball joint to the control arm.
Now in the OEM position the car knows exactly where it is based on how tilted that level arm is.
When you lower the car the arm is pushed up higher by the control arm by 2-3mm.
With that the system assumes that there is a lot of load in the rear seat/trunk and pumps up the shocks to try and level it.
To avoid that condition you have to realign the arm to the OEM position but with the new settings.
As a result I took the OEM mount which is located on the right side drop link for the sway bar....
I unbolted it, and found out that there is a locating key which is nothing more then a bent tab that fits in a square hole on the bracket.
That position retains the OEM setting.
I flattened the tab and now that allowed me to rotate the bracket down just far enough to where the compressor would not kick in under the new lowered setting.
Tightened the bolts and as soon as I sat in the rear seat the system reacted and brought it back to the preset level...
After the spring swap and adjustment on the suspension I noted that the Front sits at 26" and the Rear is at 26.25" from the ground to the highest point on the fender curve.
This way you can adjust the sensor setting for any amount of drop/lift. Another way to do is to bend the arm that connects the sensor and the control arm but that in most cases will be much more difficult to adjust.
I hope this helps, the picture below illustrates the tab that I bent.
Here is the car in the final stage... Note that the fuel tank is on E so once that gets filled up I expect another 1/4" Drop...
