hahaha you hate stock parts???? thats funny.
personally i think its stupid to spend money on all those "jdm parts" but i also think its stupid to spend the money on blue bulbs, indiglow gauges, and MADDDD neon lights.
get some seats that hold you in better and give better support, re-do the door panels, but don't do something stupid like lime green or white, that s**t looks cheap, do black, or if you must go with a color red is ok.
gauges can also make a interior alot nice, but make sure you don't go crazy and if you have a stock motor well then id say f**k the gauges cause there anit s**t you need to worry about.
aaaa damn couldn't find the pic i was looking for but ya you get the idea hopefully
