B14 without spoiler is the way to go! The factory spoiler is so boring and generic looking IMHO. When I bought my car I specifically chose one without a spoiler off the lot new!
As far as CF on a red car, I have to see it in person
Until then I am undecided.
As for painting it, I think that's a great idea. My idea for that would be to leave the flat line where the factory "200sx" logo's are carbon fiber, and use a black finisher. Paint the rest red. That shit would look killer!
