97 M3 car is 1in lower on my rear right side
 

Hey m3 fam I got a problem the other day I hit a pot hoe and I notice that right rear is lower then
My left side by a inch and a half what could it be and how much to fix and will that mess any thing else up

Something is wrong. Either get under there an look or take it to a shop.

You broke or bent something. Not way to tell how much it will cost to fix, until you find out what is wrong.

And yes, it can mess up more things if you leave it.

Yea I'm not driving it
