Realized both my sides of Roar rear side skirt have almost horizontal hairline scratches (around 1 inch plus minus) that start from the perimeter of the wheel arch.

That happen to both my left and right side.

My car is EX 1.5, GT rims 215/45/18, Tein Coilover 2 finger with camber adjusted to toe out.

Anyone with the same setup as mine had this issue? Are those scratches caused by rocks abrading the paint when they fly from my tires?
