I think I have seen the hatch and fenders in carbon fibre (but thats wide body). Dont think I have seen door skins (nor do I want to really). Front and rear bumper are best left urethane if possible, but I have a fibreglass front so I suspect that carbon will be easy. The wing however, I havent seen. I have a whaletail that is fibreglass (could have been carbon). There is also a group thing happening for a carbon fibre raised hood (vented or not) in the forums as well right now. There are also carbon fibre targas floating around, but I dont want to mess with that
All of my side trim is now painted fibreglass as well but could have been carbon fiber. I just didnt want the added expense because its getting painted. My headlight covers are also fiberglass but could have been CF. A lot of it has all been done so far with Shineauto, Retrospec, and others.
I just dont really want to go CF or FG on anything that supports the car. The fenders are a "later" project when I can go widebody (maybe 4-5 years from now)
