That Blue SI is NICE!!!
IMO, that silver Civic looked dumb. The front looked too "wide/big" and needs something to balance it out. Also that lower "lip" part of the bumper should have lines to flow into. Meaning the side skirt needs to follow the line where the bumper left off. A side with the same thickness as the little lippy part of the bumper would work nicely. I've seen some pretty bad combos of side skirts and bumpers. Unfortunately you can't test out the stuff before you buy, so you have to do you best with pictures and use good judgment. Lots of angles help too....the more, the better.
