yeah thats what i thought, i was looking at this one pair a person was selling and i put them up to my car and then didnt seem to fit on right. so i thought they had to come off, but i guess they were fake and fitmit was crap
If it doesn't fit it's not made for your car.
That's my opinion. I had some skirts once and they didn't fit. When I removed the stock black plastics there still was no good fitment. So I sent those skirts back.
