I would pass on the bumper, but I like the grille. It clearly would not fit on it's own though.
I thought Subaru did a mesh alternative grille, in fact I am sure I saw it on the Subaru OZ site before I got the sti, no longer listed now. Not available from subarugenuineparts.com either.
Anyone know where to get one?

I test fitted the lip and I am leaving it black.
