are the ABC struts affected by leaving them hang from a 2 post lift? pre thinking my winter storage.

 

Is that your only option ?
as nobody will know, I would rather keep the 4 wheels on the floor and put supports under the car just in case it wants to go down
also don't forget maintenance chargers on the batteries or disconnect and maintain them
i recently bought and tested the optimate 6 ampmatic, Its hooked up in my car permanently now. Just fabulous what those do, all automatic
