You can indeed make them look good, but i’m not so sure on the body kits thing…the basics are RS4 grill, lip spoiler, Cupra front lip, and of course wheels/suspension. Haven’t found any body kits I even slightly like, but doesn’t really need much else in my opinion anyway.
The S4 does come with HID’s stock, but unfortunately Canadians (only) were stripped of this option for some kind of DRL/legal conflict when they were released so I don’t have them.
