^ it was only in this last generation of impreza the GR(08-10) platform that STi did not share any of its body panels as the WRX. The GD(04-07) WRX and STI had identical bodies(fenders). I see what suby is doing, trying to save money by not having two sets of fenders.
It just came to me what the rear bumper of the new wrx sedan looks like....
