I prefer stock body. If it came with a spoiler, I'll leave it. If it didn't, I won't put a Ub3r jDM typ3 R y0! on it, or the m@d tyt3 jDm front or whatever. I look at things JDM for the sake of JDM as rice.
My cars have always been stock bodied, aftermarket or stock swapped wheels ,and lowered with emphasis on function > form.
My current Da9 is considered sleeper status by most. I have it supersexyslammed on old school meshies, yellow fogs and stock (yes, for now.) exhaust. I also dynoed at 18x FWHP. So it'll move out pretty decent. My places read "LSVTURD" so its possble that gives away a little bit.
