I know there are very few that have lowered their mini van's,
but of those that have...how much lower did you go?
I mean from your van height before and after.
Or did you not measure before and after?
Front lowered...?How much?
Rear lowered....?How Much?
By the way, here is a pdf I made of a lowering chart I drew, if you ever lower your car/van or do any suspension changes you want to keep track of, this may help.
