air suspension query

i have a disco with air shocks and due to my friend being disabled i need to know if there is a way of making the car drop to the floor when the ignition is turned off or by an alternative switch or control panel etc. and where a custom airbag kit can be purchased. any help will be greatly received..... thanks

what u want to do is possible if u buy a SLS remote and set the BCU to work with it:
"Remote handset SLS control
The remote handset is an accessory item which allows the SLS to be operated between normal ride height and bump stop height to allow easier connection and disconnection of trailers. The remote handset is similar in appearance to
that of the remote door locking handset but does not have an integral key. A circular button with an arrow is used to raise the SLS and an oval button with the 'Land Rover' logo is used to lower the SLS.
The remote handset control requires all doors to be closed and the ignition to be in position II, but the engine does not need to be running."
