Outer Lower Wall Trim Question

I have a question on the side trim. The side lower trim I have cut is one long piece. When I get to the area that is covered by the fenders.
The fenders seem to tilt outwards a bit (1.5mm) in that section when the trim is completely under it. Do I need to cut a section out from behind it? Ending it just at the front of fender and then continue it from back edge of the fender?
Or are the fenders still ok on top there? I was going to leave that trim our from behind the fenders but is this a wise decision?
Here is a photo so you understand my morning English (before coffee) a bit better
However that is not an up to date photo but that is the best photo I have for now.
Notice the plastic in that area where the fender sits normally.
