Not sure how the pre-facelift sits, but I know my stock bumper has a plastic piece on the bottom (fading shades of nasty white) that already sits low enough to catch curbs even with stock suspension (only did that one time before I learned my leason). From the side, you can see the front bumber is lower than the side skirts (so I have a slight snow plow look). I can't imagine the aftermarket going much lower than that, otherwise it would be straping on the ground with a 2 inch drop... haha!
