Just thought I'd add the conclusion to the supports for others who are considering it for their XF's. I did get the supports ordered, the guy from HCS made a great set. Laser cut, properly angled and bent, powder coated black, with high strength black rivets included, and the feet on the side boards perfectly fit around the punched stars without a problem. Here's a pic or two:
EDIT: the last pic looks a bit "Scratchy", the camera picked up all sorts of snow crystals and some aluminum chips from the drilling lol, the supports are a perfect gloss black contrary to what they look like lol
