I am researching mud guards for my new Macan. Looking at Amazon there are many sellers but basically it appears that there are only two styles, the ones with the 4 vertical stripes or the ones with the Macan script on the rears. My question is in regard to the ones with the Macan script. Based on the pictures shown by the vendors it appears that the mounting surface on the front guards is very narrow and you would be required to drill mounting holes into the metal fender lip. Is there enough overlap that you could secure the guard by putting screws into the plastic inner fender liner and not drill into the fender?.
