mirrors are shit, but sideskirts are factory and fuckin awesome.. not many gt-vs had sideskirts though, more a gt-apex thing.. but still factory option? and yeah us has the red side lights
as for kouki bumper, if you buy one you also need kouki grill, bumper indicators/lights, zenki lip, kouki eye lids and corner lights, otherwise it looks shit.. and if you're running kouki front bumper (bearing in mind the theme) you would also need kouki rear bumper and redlines? but redlines look shit on a silver car, i vote keep zenki
