Excluding the spoiler the black one is fairl understated i think. As long as it's for a purpose then i'm cool with the bodykits, although there are many dodgy look ones out there. At least the Japanese tend to keep the race look, whereas the Yanks have this uncomfortable mix of race/bling which i'm not keen on.
If i had the money i'd certainly go for something like the full Route KS hornet kit, i think it looks superb.
