I noticed this piece while looking to see if there where any front wheel cooling duct's for the front brakes, (there aren't ) .It feels like it has cooling fins on it but if you look behind it there is a huge piece of Aluminum welded to the bumper or sub frame and it has what looks like a 1" threaded hole through the center and it doesn't attached to the subject piece. see att pictures Thank you.long live the Z
