Okay I see I missed a question, let me first say these are stick on with the 3M tape, they go right over the original silver accents. Second, I have the molded splash guards (mud flaps) on mine. There are 2 kinds that the dealer offers, I tried the "universal" flaps first but the problem is that they don't give you a lot of space between the bottom of the flap and the ground, so basically the first speed bump you go over they will probably break off. The molded is such a nicer and cleaner look. You can see it on my picture above of my rim. Let me know if that helps or not.
