After adding my wheel spacers I started to notice I was getting rock chips near the rear door so I began looking for some sort of splash/mud guards for the model s. I was surprised to find there wasn't anything available outside of the modified universal ones. The model 3 on the other hand had some carbon fiber options. I decided to try to fabricate my own. I made a template out of cardboard then cut it out of a sheet of matte carbon plate that matched the OEM performance spoiler and my interior trim. Thought I'd share to inspire others if they are feeling handy. They are attached by 2 push clips in the fender liner locations and 3m double sided tape near the edge of the fender to help the carbon form to the contour of the fender and add extra support.
