Help-Insurance + Lowering car

I called up my insurance company this morning to change my payment options and decided to add in that my car had been lowered. I know I will be paying more but Id rather be safe then sorry if anything was to happen and I wasnt insured for it.
Anywayz, they need to know the measurement of how much more the car has been lowered compared to the standard springs which were already in it. I have no idea! Does anyone have any ideas on the measurement of standard springs and super lows?
I need to call them back this morning so help would be great!
