Heh mate got yourself a stunning sounding motor there. I'd go for carbon grey it will look well cool with the addition of the xenons.
I've got quite a few extras on mine and it's build week 28 ordered 23rd May so have a bit of a wait still on it.
Anyway for now enjoy the anticipation and don't forget to post some pics when you get it. 
Thanks for all your replies!
Rung up my dealer today and had changed my color from steel grey to carbon grey.
Pros: Carbon grey will match well with the red calliper and red stripe. Don't think steel grey will blend well with the black side skirts and the lower arm of the side mirrors!
Cons: Parking dent and stone chip stood out a bit more than lighter color
Need cleaning every weekend!
Will post pictures once I pick up the car and give it a good clean!
