MDI CarbonFiber provided most of my cf, they have an eBay store. I don't have time this morning to mess trying to get links to format properly on this website.
MDI's cf is vacuum pressed and very high quality. You have to watch them though, they do a terrible packing job and I have had to send back an upper cowl and two main side cowls and the tail cowls for replacement because they didn't pack them well enough and they got marred and even a few cracks from package damage. But they provided good replacements, and the cf is gorgeous thin.
Warning on MDI CarbonFiber, somewhat on others, don't expect it to go on like OEM plastic. The belly cowls don't meet at the bottom front right, due to mold distortion. You'll need a rat-tail file and probably a dremel, and any hole a wellnut has to go in, you'll need to drill out slightly. They make the holes in the mold smaller expecting cure shrinkage, but they err on too small because it can always be drilled.
My tail pieces (2, holds the turn signals each side) don't have proper staunchions to hold the wellnuts to which the turn signals are bolted. I had to drill them out *carefully* to get the wellnuts to push down in them.
Above all, cf is NOT like OEM plastic. You will have to modify it to get it to work quite often.
Powerbronze has some good pieces, but limited, and expensive.
Bestem is also on eBay, I got my belly cowl (left, right) from them because everyone else wants you to buy the rear belly cowl (1 piece, have to remove for center stand) as a 3-piece package. No thanks, and eventually I'll put a center stand on anyway.
