2017–2021 Audi A5 S-Line / S5 / RS5 B9 / B9.5 Coupe Rear Trunk Spoiler Wing Lip – Carbon Fiber

Elevate the rear roofline and trunk lid of your Audi A5 S-Line, S5, or RS5 B9 Coupe with this carbon fiber rear trunk spoiler wing lip. Molded for the factory trunk lid, it adds a purposeful, performance-inspired finishing detail that complements the flowing Coupe roofline with a genuine carbon weave finish.

Build

• Material: Genuine carbon fiber, autoclave cured and vacuum moulded using a 3D design and CNC moulding process for precise spoiler geometry, consistent panel quality, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
• Surface finish: High-gloss epoxy-polished top coat that showcases the natural carbon weave and provides lasting UV and moisture protection through sustained outdoor and driving exposure
• Configuration: Single-piece spoiler wing lip
• Weight: Lightweight carbon construction adds negligible weight to the trunk lid

Design & Finish

• Refined rear detail: Subtle wing lip profile adds a purposeful, performance-inspired finish to the trunk lid without overpowering the Coupe's roofline
• Carbon aesthetic: Directional weave and gloss finish complement the factory B9 Coupe body lines for a coordinated, motorsport-grade look
• Factory-style integration: Precision-molded to follow the contours of the factory trunk lid for a clean, seamless fit

Package Contents

• 1 × carbon fiber rear trunk spoiler wing lip
• Adhesive tape for installation
• Mounting screws for installation

Installation

• Two mounting options: Fit with the included adhesive tape for a reversible install, or with the included screws for a more permanent, secure fitment
• Surface prep: If using adhesive tape, thoroughly clean, degrease, and dry the trunk lid at the spoiler position before fitting to ensure maximum adhesion
• Alignment: Dry-fit and check the spoiler sits centred and symmetrical across the trunk lid before committing to either method
• Professional installation recommended for correct positioning, panel alignment, and finish — particularly if using the screw-mount option

Before You Install

• Confirm your car is an A5 S-Line, S5, or RS5 B9 or B9.5 Coupe (2017–2021) before ordering — this will not fit the Sportback, Sedan, or Cabriolet
• Screw mounting is permanent — it requires drilling into the trunk lid, so decide on your method and confirm placement before starting
• Work in moderate temperatures and allow the adhesive to cure fully before washing the car
• Adhesive installation is reversible, but removal and re-prep may be required if the spoiler needs repositioning
