I have these on mine. They look great, don't look like an add on. Fit is perfect, although if you have rear mudguards fitted you will need to trim them slightly with a sharp knife. As you say, lots of drilling holes and plastic push rivets!
Darn, another thing to add to my list now, if I can find the rear only, I see many for pre 2012 but I assume because of the front bumper change. I don't think the rear lower valance changed during the facelift on non R Line.. It would really look good since the front already has the silver fake crash guard look..it looks really good N4S, I am also debating on the LED conversion for the reflector strips while I am running wires.. tie them into the Marker Lights..
Thanks Shaun170, yes i cut out just enough of the marked area to install my hitch. the panel would of been nice..be interesting to see how it looks with the hitch fitted.. I went with the Curt Class 3 2" hitch.
