Sharpen the lower rear profile of your Audi A4 B9 S-Line or S4 B9 Sedan with this genuine carbon fiber sport rear bumper lip, precision manufactured using a 3D design and CNC moulding process with full autoclave curing. Designed specifically for the S4 B9 factory rear bumper, this sport bumper lip adds a wider, more aggressive lower rear appearance with a high-gloss epoxy polished and UV-protected carbon fiber surface that showcases the natural carbon weave in exceptional detail. At 135cm wide, the lip delivers comprehensive lower rear bumper coverage for a more planted and performance-oriented rear stance on the A4 B9 S-Line and S4 Sedan platform. Both adhesive tape and screws are supplied to accommodate either a clean reversible installation or a more permanent fitment depending on individual preference.
