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

Are OEM products more expensive than aftermarket alternatives?

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
