Can you post a diy or take some pics of the cut out. I want to do a quad cut out for mines but dont know where to start. |
I should've taken pics but I was in a hurry. It was not tough though. The diffuser is just a few 8mm hex bolts and some fasteners you can pop out with a screwdriver. Just be careful with the parking sensors. What I did was make a template of the oem cutout with a piece of cardboard. I then traced it with marker on the opposite side, measuring at each point to make sure it was identical. I used a dremel cutting tool to roughly cut the shape, leaving about a half inch of margin. Then I used the sanding tool to even it out. Finally I used some finishing sandpaper to get it smooth. It really was much easier than I thought.
