Following up on my last post, today I received and installed my Automotive Passion mud guards. As I had planed, I successfully installed them inside the wheel well liner. All I had to do was make a small (about 4 inch) scissor cut on the lower section of the from wheel well liner to allow the flap to pass through. I also drilled a small whole in the liner to secure a fastener for the top hole. No modifications were needed for the rear mud guard installation. As predicted, wedging the mud guard flap between the wheel well liner and the fender, makes for a more firm installation. I also like the more integrated look of this alternative. Here are some pictures of the result:Yes, I had noticed and it's true for the front, but not so for the rear well liner. Even so, as relates to the front wheel well, that liner seems to be made of some sort of soft plastic/fiberglass material and a small channel could be cut to allow the mud guard bottom edge through. Coincidentally, I sent a message to the folks at Automotive Passion to get their input on this. I ordered a set, so I will probably give this Idea a shot, unless Automotive Passion comes back with a good reason not to. The uncertainty I have at this point is what exactly is behind that section of the liner, but it's easy to check beforehand anyway, since it can be sufficiently pulled out to check once the pop rivet plugs are removed. Will revert with my results later on.
