How do I remove these front undercarriage fasteners?

How do I remove these front undercarriage fasteners without butchering to install after-market spoiler. Not allen screws. TIA.

Thanks for the graph! Another source said it might be a rivet that would have to be drilled out. Will check this info out. Wanna do least damage.

That plastic strip is installed by the dealer as part of pre delivery.
Some people have found it uninstalled in the trunk/boot, some have not received it at all

It should be pretty easy to remove.

It is not easy to remove. I installed mine myself. They are METAL tri-fold rivets that hold it on there. You would have to drill them out / grind off the heads and somehow get the pieces that riveted behind the plastic out by somehow removing the plastic shield it is attached to. You could really mess it up if you are not careful.


Here are some pix from
My install. I also talked about this on page 19 when I joined the forum here:

You can see you cannot use an allen or anything to take them out because in that hole is a metal post. I did lots of googling to see how these work. But just look up how to remove a tri-fold rivet. Here is a short that shows something very similar.

With "drilling out" I too am worried about that much shrapnel rolling around loose in the front end. Might end up working around the piece. Thanks again for the insight.

No problem.
It's why I thought long and hard about even installing it but ultimately decided I liked the looks of it more on instead of off.

If you find a good way to get it off I would be curious about it in case I ever decided to remove mine too - though I don't see that happening unless it gets damaged or I find another chin-spoiler that I think looks better.
