hey bro!! i suggest that you dont go for it.. why? because i live in malaysia where there are plenty of fibre body works (because the original bodykits are way to expensive, i think i told u that before!!
so, one thing is, for M3 bumpers, it is a one piece bumper. Meaning, it will be very obvious when u spray paint it. The picture you posted is may not be a legit one as the bumper lip (which is supposed to be a separate one if its original) doesnt look like its one piece. Trust me, ive seen alot of fibre m3 bumpers over here in malaysia, and they are just not worth it. Because its an obvious fake. Trust me on this, it will look ugly..
That's why i opt for ACS bumpers and not M3, because acs does not have any separate pieces.
AND, USD180.00 is TOO DARN EXPENSIVE.. man, 7layers of fibre? so what? it is still the same dude..it is still fibre..
AND, if the the fibre mouldings are too thick (too many layers) , it is a well known problem as it wont have a direct fit, because the size is too big. A few of my close friends all had this problem fitting replica fibre M3 bumpers.
