I've got a set of Speedfibre '04 RSW 250 bodywork on my RS250. It's quality stuff, but then it cost a fair mint aswell! Must be some of the best glass fibre I've seen, super thin, but really well finished.
I did look at getting the CF stuff, but it comes pre finished in white as it's so thin that light passes through it. Apparently Speedfibre thought the thinness made it look poor quality. Anyway, they only reason I'd get CF was to show it off and seeing as it's pre painted didn't seem worth the huge expence. I'm soooooo shallow!
Ian Emberton is a great guy, didn't mind me ringing him up and shooting the breeze about this RS bit or that RS bit. Top bloke.
