In a nutshell... I would strongly recommend upgrading to S14 seats, or at least having the stock seats redone. Nissan did a very poor job with our interiors.
I see a lot of small carbon fiber pieces on the internet.... shift rings, stereo surrounds, center consoles, gauge bezels, etc... I once saw and entire dash in CF.. very pricey! Keep your eye on ebay for some little CF touches to help freshen things up.
