The only thing "looks wise" RacingLine has are the interior LED's and the battery tie down I think.
As for the Nismo badges, I like what you did, especially the sides, never thought of that myself, although I was going more for a minimalistic approach. And FYI, anything "aftermarket" that's done to a Nissan car is considered "Nismo". You don't have to just have a Nismo exhaust, although it does help add to the overall look.
