I have always fancied a diffuser to finish off the back end of my NSX, nothing more than a cosmetic update, and maybe in fact more problems for me having a slightly lowered suspension with speed bumps.... but what the hell.
Ive seen this diffuser at 1:17 mins on this film http://www.youtube.com/watch?v=X-W_K...rec-r2-2f-2-HM
and wonder if anyone knows if its homemade or maybe commercially available or if in fact there are any tried and tested ones for the NA1?
