Im sitting on the fence with this... just a few questions.

wondering what the advantages are?
what I would need to get to go along with the kit?
Also if I install this then install a lift, what would change?
would it be better to not install a lift with this or would it not make a difference?
what kind of air system would be best suited to go along with the air switch?
heads spinning
sorry for the crazy questions but ive been thinking about this ever since you announced that you were making kits.
