Those all red ones look kinda gross. Way too thick and doesn't have the clean factory appearance.

Yes you can paint the factory side skirts. I've seen many sols that had them done. IMO it doesn't make that much of a difference, but then again, I've only seen them in pictures and I know in person it would look better.

Get a Civic lip, paint side skirts and then get some S2000 or WRX side strakes and MAKE them fit somehow . Then do something with the butt. I like the extreme rear bumper without the whole bumper painted. Leave the middle section black. I don't know how that'll line up with the stock sides but even the stock rear bumper is too high.
