They are fairly easy to put on nothing funky with them when I put them on 17. One thing to be aware of, they are longer than your average flap so be careful backing up to a curb you can catch flap between the curb and the tire with a high enough curb. Not really a real issue unless you start climbing the curb
Thanks for the heads up. How far off the ground did you put them? Did you have to shorten yours?
Mine were predrilled, so there wasn’t any adjustment without drilling. I did drill and raise them about an inch.
Be sure the screws are tight, I never could keep them tight on my 05. The rigid flap vibrates more, which is why I think the screws were always loose. I lost one on a road trip and pulled the other 3.
