2014–2018 Audi RS7 C7 4G Sportback Factory Style Rear Bumper Diffuser – Dry Carbon Fiber
Transform the rear profile of your Audi RS7 C7 4G Sportback with this dry carbon fiber rear bumper diffuser. Molded to the factory RS7 diffuser silhouette for the factory rear bumper, it sharpens the lower rear end — visually widening and lowering the rear stance for a more aggressive, motorsport-inspired presence with a genuine dry carbon finish.
Build
- Material: Genuine dry carbon fiber, autoclave cured using a 3D design and CNC milling process for a tighter, more consistent weave and a superior strength-to-weight ratio compared to standard wet carbon or carbon-look alternatives
- Surface finish: High-gloss epoxy-polished top coat that holds its deep dry carbon appearance through sustained outdoor and driving exposure without fading or yellowing
- Configuration: Single-piece diffuser for the lower rear bumper
- Weight: Lightweight at approximately 2.7 kg
Design & Aerodynamics
- Factory-style profile: Faithfully replicates the factory RS7 diffuser silhouette, preserving the original design language while upgrading the material to premium dry carbon fiber
- Aggressive stance: Visually widens and lowers the rear stance for a more track-inspired rear-end presence
- Carbon aesthetic: Refined dry carbon weave and gloss finish complement the RS7's factory bodywork for a coordinated, motorsport-grade look
