2008–2012 Audi A4 S-Line / S4 B8 Sedan Rear Bumper Lip with Integrated Brake Light – Carbon Fiber

Complete the rear-end styling of your Audi A4 B8 S-Line or S4 Sedan with this carbon fiber rear bumper lip featuring an integrated brake light. Spanning 142.7 cm across the lower bumper, it adds a wider, more aggressive lower rear appearance while incorporating a functional brake light for added rear visibility.

Build

• Material: Genuine carbon fiber, autoclave cured using a 3D design and CNC moulding process for precise lip geometry, consistent panel quality, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
• Surface finish: High-gloss epoxy-polished and UV-protected finish that showcases the natural carbon weave and resists UV exposure, moisture, and surface degradation through sustained outdoor and driving use
• Integrated brake light: Built-in brake light combines the visual upgrade with added rear visibility
• Panel width & weight: 142.7 cm across · approximately 1.25 kg

Design & Function

• Aggressive stance: Lip profile adds width and visual weight to the lower rear for a more planted, track-inspired rear end
• Integrated brake light: Adds a functional lighting element to the rear bumper alongside the styling upgrade
• Carbon aesthetic: Directional weave and gloss finish complement the sporty S-Line and S4 bodywork for a coordinated, motorsport-grade look
