since your going for a clean style that will not "let rain in" or "just look plain ricey" i'd say get a regular OEM CF one, there is no harm or foul in it, and it always looks clean, granted you don't get the same reaction when you have no scoops or anything but seriously it saves you alot of hassle and always has clean lines. i thought about doing the jdm class @ nopi also, there is alot of competition in the jdm classes now a days, especially with the honda and nissan crowd.... mainly EG, EK, S chassis, and what not, but you do have a nice ride, so i say go for it! best of luck!
