Second, to prep the diffusers, you sand, degrease, and paint - with that front lip, you need to add several more time consuming steps and materials such as epoxy primer (messy stuff). Lastly, the diffusers FIT, like OEM factory fit because they were made by Daimler-Chrysler, the cheaper Chinese copies they have produced since do not fit well at all.

I am not trying to rain on your parade, but by the time you have all this time and money invested into forcing a slip on to work, you could have bought an SRT front end with OEM fitment and have it look awesome and not have any screws in your bumper or worry about this thing flying off at 140 MPH. If someone made a lip for the XF that was like this, but a direct fit for between $50-$125 it would sell all day.
