I checked pics of your car often
I saw on your car the kaminari skirts don't use screw in the door-hole. Isaac has 4 screws there according to his install guide. I was hoping not having to drill there.
Thankfully I was right.
I found the following pic of your car, showing the screws in the front of your right skirt. You can see it's drilled in the front indeed. I will try to drill the screws in the skirts, plastic won't rust...
