2019-2026 Audi RS6 Avant / RS7 C8 - Dry Carbon Fiber Rear Diffuser w/ Corner Spats


Product Features

  • Aggressive Motorsport Rear Stance: Dramatically transforms the rear profile of your RS6 Avant or RS7 with deep aerodynamic fins and an aggressive lower valence that highlights the car's wide-body posture.

  • Autoclave Pre-Preg Dry Carbon Fiber: Manufactured using high-pressure autoclave pre-impregnated dry carbon fiber technology, yielding maximum structural rigidity with the lowest possible weight and zero excess resin.

  • UV-Resistant High-Gloss Finish: Sealed beneath a deep, mirror-like UV-protective clear coat formulated to resist yellowing, hazing, or thermal degradation from exhaust heat and sun exposure.

  • Underbody Airflow & Wake Optimization: Sculpted channels manage turbulent underbody air as it exits the rear of the vehicle, actively reducing high-speed aerodynamic drag and lift.

  • Precision C8 Laser-Scan Fitment: Molded from 3D digital scans of the OEM C8 RS rear bumper assembly to ensure clean alignment with factory mounting tabs, underbody splash guards, and signature oval exhaust tips.

  • Exotic Performance Replacement: Replaces the standard plastic lower valence with a high-end composite piece that completes an authentic track-inspired carbon fiber exterior package.
