I wouldn't risk the increased chance of bottoming out by lowering a Civic. Speed bumps are going to be a nightmare too and it could damage the underside. This is great if you plan to go on track, but not really for the average sedan owner.
i'm going to assume he's on air...and that is lowered for parking purposes. that is really low for daily driving. however, he does have the clear sidemarkers. all blacked out grille. he's done some subtle mods to this.
I actually wouldn't be surprised if these guys were on coils. Wouldn't be the first time seeing extremely slammed cars that were static that looked completely undrivable or practical for getting down a non-freshly paved street.
