IMO, yeah you can have to much CF, it really just depends on where you place it on the car. I myself own a White SS/TC, My plans are to place on the car:
Carbon Fiber Front Bowtie
Carbon Fiber Mirror Covers
Carbon Fiber Wing Center/End Caps
Carbon Fiber SS badges
Carbon Fiber Interior Trim
Headlights with Carbon Fiber housings Which i'm praying will be possible haha, I think Cesar can do it though
IMO thats not to much, its just going to basically accent the car and I should end up with the nice clean look that i'm going for once I include the bronze wheels (Y)
