i was wondering the same thing, what makes it only work for 2DR. the wholes is not something im worried about, im wondering if its the width of the spoiler that make it not fit.
that spoiler you posted cortez is actually a little bit different from the one in the picture but it is somewhat similar.
this is the one on andysautosport "black widow style'
and heres a extreme dimensions spoiler.... looks 100x better.
if anyone knows if it will fit let me know!
