Thanks for all the input guys, it sounds like the carbon look is in this year.
I'm still not entirely convinced but I think I'll try fitting it up int the raw CF first and see how it looks. I should get it done by the weekend, work commitments permitting.

I suppose for those that just want the 'look' you could just paint the wing black, or dare I day cover it with that faux cf film - done properly of course using the high quality stuff applied with a heat gun to get it to follow the contours properly.

Stryfox: This has reminded me... I seem to recall someone, I'm sure it was you, painting your roof a high gloss black to blend into the glass area, did you keep it that way?

Thanks jonny, I'm going as fast as I, should have news on the exhaust soon.

Srt_crossfire: I've not even seen an SRT in the UK yet, they are RARE! In terms of getting a CF spoiler I have hand laid mine in a GRP mould using epoxy and raw matting, vacuum bagged while it cures. The pro's would make an aluminum tool and lay it up with pre-preg mat and set it in an autoclave. I can only suggest you try a local outfit that produces CF mouldings for race cars etc, or alternatively try a local boat builder - they use all the same materials but you tend not to get charged the 'motorsport' prices! Either way it will probably be prohibitively expensive and you may have to sacrifice your stock wing in the process. I quite like these sort of 'why would you bother' projects though because by definition you end up with a lot of cool stuff that no one else has.
