This is what I'd do...
My thoughts for the Glanza body work wise is the following:
Respray in midnight purple (Nissan GTR colour)
Carbon fibre wings,
painted (Bear with me on this one )
Carbon fibre front splitter
Carbon fibre
bonnet (Stock style, no reverse scoop)
Carbon fibre spoiler
Now, the wings. Why paint them? Well, TBH, that R34 looks pants with unpainted CF wings.
However, they have vents on them, so why not do something like this...
What they've done there is paint the CF bonnet, but leave sections (ie, the vents) unpainted, giving it a carbon insert look. If the CF wings are styled like the ZEP Racing ones, you could do a similar idea.
Damn I'm a fucking genious sometimes
