If I were you I wouldn't paint the car to go with the white rims if you really dont care for the rims. Find a set of rims that you REALLY want and paint the car to go with them then save and get them. If you are already set on painting the car blue I would recommend estoril blue from the beemer...
Even if you do find and buy a DRY carbon fiber hood it will still have to be prepped and probably primed before it is painted so there really wouldn't be any difference in getting one that is already cleared and sanding it. Oh yea... FYI a dry carbon fiber hood would probably be more expensive...
Old news and no those aren't autozone covers. Jeff99GS hit the nail on the head. The bolt-on spinner kits come with their own special lugs for mounting the spinners.
