Just received these. The foam tape that comes with is completely useless as the adhesive is already pulled away from the foam. Don’t know if that matters though because the inside edge rim is scalloped and not evenly flat. So if you put foam tape it will not evenly seat against the rim. You would need to alternate between 1mm and 3mm foam tape in order to achieve even pressure around the wheel. Also the ABS is not “black” it is more of a brownish-grey-black. It will look good but it won’t match true black on the car.
