Tidy.
Mine are going a candy apple red, with gold brembo lettering, to match the engine bay also. (candy red cam covers, coildpack cover and gear cover) with gold R34 V-spec GTR badge on the coilpack cover.
Its all about keeping the car to a theme... and limiting it to a main colour, with one or two accents. In my case, black car, candy red accent with gold details.
