Are 05 and 06 Stillen Mud flaps still available? I have searched all over and I don't want to take a chance and buy some truck mud flaps!
Had these on our car since 2007, all rally track days too. The make a scary noise when they touch a speed bump (but have never had any issues
Thinking about it more, (note, I installed these circa 2008), For the rears, there are no mechanical fasteners just the tape. I added some silicone caulk, not only to add some adhesion, but also seal out any opportunity for dirt / grit to get in between the piece and the car. In my case used black, and its invisible (black car).
Fronts are rock solid, and can be removed easily for inner finder removal, etc.
