Awesome thread OP!! I have read every single page and sorry if i post some stuff that has already been said but... How about pullies, lowering springs, motor mounts, diff mounts, turbo timer, i have a blue apex'i in my 350z and its on nitrous only, it looks sick and people are always asking what it is and what it does... This is still a good mod even if your not forced induction, its always good to let your car cool down after a hard run. This mod is kind of bad lol but i have a kill switch for my windows because i have 5% tint on them so whenever i get pulled over, officer asks me to roll up the windows and i pull the "darn the motors went out again" card... works everytime haha. Im just throwing out ideas that i have done on my 350, torque damper? Not sure if there are any makers of this yet for the 370... nismo valve caps, front strut bar, gt spec under braces, race gas
lol. Muffler delete, painted door handles, cf wrapped A and B pillars... Im about out of ideas lol
