Ha! I remember removing that stuff on the Z3’s- there was a bulletin where they would wrinkle and the fix was to just peel it off and not replace it. I think the later ones stopped coming with it installed at the factory.I find this funny as the Z3 guys (I’m one) have always removed the factory black tap to the pillars and Headers. There are are factory color but covered in black and now Mustang people (I’m am one) are going the opposite!
