Weird. Then maybe I was sent the wrong passenger's side then.
You know, I'm wondering if the strut braces on the M3s with electronic dampening have different parts.
Look at the Passenger's side strut brace. (First Pic).
See how narraow the slot is?
On the Dirver's side, the slot is wider to let the part circled in yellow to fit in the wide area.
On the passenger's side, all slots are narrow.
