Yeah, Mark from SlideSquad's S13 was stupid nice... never cared for the mis-matched rims, but it was still a nice ride. So much so that it compelled me to buy a S13 240SX so I could make myself a Silvia. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>
Anyway, that bumper looks aftermarket, as others have already pointed out. Not an aero cus of the lip, and not a K's cus it has a vent on the left side (K's only have vents on the right side).
Q's have no vents.
