I have the cervinis bumper and if I had to do it again, I would just put up the extra money and get the ford 01 cobra bumper and cobra r splitter. That way you can remove it if you want. Also the fit of the cervinis bumper was pretty awful, and it still doesn't line up perfect. It was a total pain to paint, the oils kept bubbling up through the paint. I don't know what the ford stuff is like quality wise, but I was pretty disappointed with the cervinis stuff.
