2019–2021 Audi RS6 / A6 C8 Avant Wagon Rear Bumper Diffuser – Dry Carbon Fiber
Complete the rear-end transformation of your Audi RS6 or A6 C8 Avant with this dry carbon fiber rear bumper diffuser. Spanning 156 cm for full-width lower coverage, it adds width and visual aggression to the factory rear bumper for a more planted, performance-oriented stance, finished in genuine dry carbon.
Build
- Material: Genuine dry carbon fiber, autoclave cured using a 3D design and CNC milling process for a superior strength-to-weight ratio, tighter weave consistency, and a more refined surface than standard wet carbon or carbon-look alternatives
- Surface finish: High-gloss epoxy-polished top coat that showcases the natural dry carbon weave in detail and provides lasting UV and moisture protection through sustained outdoor and driving exposure
- Configuration: Single-piece full-width diffuser for the lower rear bumper
- Dimensions & weight: 156 cm wide · approximately 1.15 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 156 cm span covers the complete lower rear bumper for an integrated finish with no exposed factory sections
- Carbon aesthetic: Refined dry carbon weave and gloss finish complement the factory C8 Avant bodywork for a coordinated, motorsport-grade look
Fitment
- 2019–2021 Audi RS6 C8 Avant (4-door wagon)
- 2019–2021 Audi A6 C8 Avant (4-door wagon)
- Fits the factory C8 Avant rear bumper only — not compatible with aftermarket or non-C8 Avant bumper configurations
- Body style: Avant (wagon) only — not confirmed for Sedan body variants
Package Contents
- 1 × dry carbon fiber rear bumper diffuser
- Pre-applied adhesive tape for installation
Installation
- No-drill, adhesive-mounted: Installs with the included adhesive tape — no drilling and no permanent modification to the factory rear bumper
- Surface prep: Thoroughly clean, degrease, and dry the rear bumper before fitting to ensure maximum adhesion
- Alignment: Dry-fit and check the diffuser sits centred and even across the bumper before final adhesion
- Professional installation recommended for correct positioning, panel alignment, and finish quality given the 156 cm panel width
Before You Install
- Confirm your car is a C8 Avant wagon (2019–2021) before ordering — fitment is not confirmed for Sedan body styles
- Measure from fixed reference points on both sides before adhesion; a full-width panel shows even small asymmetry clearly
- Work in moderate temperatures and allow the adhesive to cure fully before washing the car
- Installation is reversible, but adhesive removal and re-prep may be required if the diffuser needs repositioning
