I'll take one, as I dont own the car, but #3
carbon fiber can start to fray or seperate a bit if not sealed. And hit or abrasion will accelerate it. Basically, sand it edges smooth, not going to too much extreme, but get rid of burrs. apply super glue with a cue tip or tooth pick to the edges to seal and strengthen the edge. Helps keep it from cracking and spitting. Cheap insurance. Time consuming, but well worth the effort.
