asking specifically about the KYB AGXs, when you buy aftermarket shocks, are they designed so that the area where the spring sits is the same height as the stock shocks?

such as: if i have stock shocks with, lets say, HR OEM springs. will the setup yeild a lower ride height if i mated those springs with an aftermarket shock?

i know the koni yellows have adjustable perches, but what about the shocks that dont.

kinda hard to word the question, you get my drift? thanks.
