Air ride and drop spindles

[Foxchapeliron]

Have a suspension dilemma..... I have a 72 chevelle currently with stock a-arms but I have drastically lowered the coil springs to test if my 20" fronts and 22" rears would clear. They do. However, I am basically riding on the bumper blocks.

Now, to get a taller stance while driving vs the slammed stance when parked I am looking at Ride Tec's shock wave level two system for front and rear air ride. New a-arms, tracking bars, etc. What I am not understanding that they keep telling me is that I don't need drop spindles for their system. To keep the stance low I am not understanding how the sweet spot of the suspension is going to operate up front without dropping spindles and getting into the travel range of the suspension. I guess what I am struggling with is the mount points of the a-arms and the spindle total length will not change, so how do you not basically bottom their suspension range if you use stock spindles???
