I have active power stabilizer suspension system (apsss) and adaptive variable suspension (avs) in my gs450h. With apsss as an option am I able to change to coilovers or change the springs of the suspension without losing the two functions?

I know I have apsss because the motors and batteries in the spare tire area in the trunk. I really enjoy being able to throw the car around in turns and have little to no body roll but I wonder if this is as good as it gets for this platform when you have (apsss)

I appreciate the help in advance!
