recently bought an oem aerodynamic diffuser lip for my car and just not coming with screws. Just wondering if someone can provide the install instruction for this part?
Sorry, I don't have actual installation instructions, but I took some pictures of mine. Yes, the bottom part screws on in several places. There are screws where you have your circles. But then it's also screwed on forward by the wheel, and then two screws for each of the fins. The part above the exhaust tips I assume is just stuck on with double sided tape. But the bottom part like the OE aero front splitter is securely screwed on to make sure it doesn't come off from the air pressure. I'm assuming the diffuser and the bumper have the appropriate holes for it if the car was ordered with the aero package.

Also, I stuck my fingers in there trying to see what these screws go into, but it's all enclosed. Even the one on the side that goes into the bumper, there's some kind of a plastic or hard foam buildup. Not sure if these are self-drilling/self-tapping screws or if there are metal threads already on the other side integrated into the diffuser and bumper and as you can see I have the carbon fiber diffuser, which could be different.
