Last night I installed Rally Mud Flaps on my 2011 WRX 5 Door. To my suprise while installing them in the rear, When I pulled the Bumper Cover away, about 5 pounds of dirt fell out of it, and that happened on both sides of the car! I've never seen this before on previously owned vehicles of mine. I checked out the rear wheel well and nothing looks like it's ripped or anything so I'm dumbfounded as to how it got there.
Has anyone else seen this?
