If added after production it rarely serves a purpose. I have full CF door panels, and I guess they serve a purpose because they drop 5lbs a door, and they look fantastic! Any trim added in CF will not save any weight, but I want my car to feel more sporty than touring. Also, because my doors are CF, I need to swap out the leather. I could put aluminum or painted trim, but for me the focus is the carbon weave, and I feel anything else will detract from that. The good thing with trim is it is on the cheaper side of modifications and it is easily interchangeable. Maybe I will get LSB trim as well to change it up every few weeks. That's the beauty of plug and play trim.
