Frequently Asked Questions
2013–2016 Audi A5 / S5 8T Facelift Rear Bumper Diffuser – Carbon Fiber
Upgrade the lower rear profile of your Audi A5 or S5 8T Facelift with this carbon fiber rear bumper diffuser. Spanning 152 cm for full-width lower coverage, it adds width and visual aggression to the factory rear bumper for a more planted, performance-oriented stance in a deep gloss black carbon finish.
Build
- Material: Genuine carbon fiber, manufactured to precise tolerances for consistent panel quality, high structural integrity, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
- Surface finish: Deep gloss black finish with a UV-resistant coating that showcases the natural carbon weave and resists UV exposure, moisture, and road debris through sustained outdoor and driving use
- Configuration: Single-piece full-width diffuser for the lower rear bumper
- Panel width & weight: 152 cm across · approximately 4 kg
Design & Aerodynamics
- Aggressive stance: Diffuser profile adds width and visual weight to the lower rear for a more planted, track-inspired rear end
- Full-width coverage: The 152 cm span covers the complete lower rear bumper for an integrated finish with no exposed factory sections
- Carbon aesthetic: Directional weave and gloss black finish complement the factory 8T bodywork for a coordinated, motorsport-grade look
Fitment
- 2013–2016 Audi A5 (8T Facelift)

- Fits the factory rear bumper only — not compatible with aftermarket bumper configurations
- Not compatible with the later B9 generation A5 / S5
Package Contents
- 1 × carbon fiber rear bumper diffuser
- Installation hardware
Installation
- Surface prep: Thoroughly clean and degrease the rear bumper before installation to ensure correct panel seating and secure fitment
- Alignment: Dry-fit and check the diffuser sits centred and even across the bumper, with consistent panel gaps on both sides, before final fitting
- Professional installation strongly recommended — a panel of this size and weight requires careful positioning to achieve symmetrical alignment and a clean finish
- Plan for a second pair of hands during fitting given the panel's width and 4 kg weight
Before You Install
- Confirm your car is the 8T facelift, not the pre-facelift model — the pre-facelift rear bumper is a different profile and this diffuser will not fit it; check your build date if you are unsure
- Verify your factory rear bumper is unmodified before ordering
- Take care when parking rear-in — full-width lower rear panels sit close to kerbs and parking blocks
