Paint lower plastic trim.

[SwissXC90]

Look up in VIDA by year.

They are called Mudguard wideners

There are different Mudguard widener sizes, 4 in total (Type A narrow to Type D wide), and then left and right, and then painted vs unpainted.

Here's a VIDA lookup for you, as a pure comparison, for my car

2009 XC90, with black plastic wheel arch extenders. I have Type C I think, unpainted.

When comparing to your car, make sure you take the CHassis number into account.

Not yet, I have talked to a few paint places and the seem to think they do these with out issues but special products have to be used due to the textured finish.

When I decide to do this I will inform.
