...major forum for serious nissan guys... great bunch of people there, lot of people who know whats up, but very friendly group of people to the new guys. only problem really with NICO is they are not too friendly to serious ricers (huge wings, excessive stickers, etc.) (which is good, keeps the showish people out of our turning forums)
