Izzy - Yes, they are only brake covers. I don't think they make a Brembo brake kit for the 2013+ MKZ's.. at least whenever I did a search on them, I couldn't find any. I have been wanting a simple cold air intake and I can't even find a company that makes those either.
Kramf - A couple of years ago, I wanted a side badge that resembled the new Lincoln Continental & Navigator side badges but could never find any. About a month ago, I came across this one and to answer your question, yes, it does say Lincoln. Bought it off eBay for $46.
