Rear Trunk Spoiler Carbon Fiber for 2017-2023 Audi A5 Sline S5 RS5 B9 B9.5 Coupe

Rear Trunk Spoiler for 2017-2023 Audi A5 S-Line / S5 / RS5 B9 & B9.5 Coupe — Carbon Fiber or Glossy Black FRP

The Audi A5 B9 Coupe's fastback-influenced rear deck features a clean, tight trunk lid trailing edge that follows the Coupe's long roofline arc — a surface that benefits from a low-profile trunk lip spoiler that extends the trunk lid's trailing edge in carbon or gloss black, adding rear downforce and a purposeful trunk accent consistent with the A5's GT-sport character. This rear trunk spoiler is designed using aero simulation and CAD technology to follow the exact trunk lid curvature of the B9/B9.5 A5, S5, and RS5 Coupe, adding downforce at the trunk's trailing edge without obstructing the driver's rearward sightline through the rear screen. Tape-on installation, no drilling required. Fits B9 (2017–2019) and B9.5 LCI (2020–2023) Coupe.

Why This Spoiler Fits the A5 S-Line, S5, and RS5

The B9 A5 S-Line, S5, and RS5 Coupe all share the same rear trunk lid geometry — a unified trunk deck surface across the B9 platform's performance variants. Audi Sport's own RS5 Coupe Competition Plus package includes a carbon fiber rear spoiler as a factory option, using the same trunk lid mounting position as this aftermarket unit. This spoiler delivers the RS5 Competition Plus carbon spoiler aesthetic to any B9/B9.5 A5 S-Line, S5, or RS5 Coupe at a fraction of the OEM option price.

Choose Your Spec

• Carbon Fiber ($277.99): Genuine 3×3 twill weave carbon fiber with UV-gloss double-layer clear coat. Real carbon construction — not ABS with carbon wrap. Matches the weave and gloss of any other B9 carbon exterior components. Recommended for RS5 and S5 builds targeting the Audi Sport carbon exterior specification.
• Glossy Black FRP ($170.99): Fiberglass-reinforced plastic in a high-gloss black finish — same precision B9 Coupe fitment at a $107 saving. The gloss black finish coordinates with the A5/S5's available Glacier White, Navarra Blue, and Mythos Black exterior colors and works as a base for body-color paint or wrap.

Key Features

• B9 & B9.5 Full-Platform Fitment (2017–2023): CAD-engineered and real-car tested for the Audi A5 S-Line, S5, and RS5 B9 (2017–2019) and B9.5 LCI (2020–2023) Coupe — all variants share the same rear trunk lid trailing edge geometry. Double-sided tape included — no drilling, no modification to the factory trunk lid surface.
• Aero-Simulation Designed Profile: Spoiler profile engineered using aero simulation and CAD technology to follow the B9 Coupe's trunk lid curvature — reducing rear drag and increasing rear downforce at the trunk's trailing edge without obstructing the driver's rearward visibility through the rear screen.
• Genuine 3×3 Carbon Fiber (CF variant): Premium 3×3 twill weave carbon fiber with UV-resistant high-gloss double-layer clear coat. Real carbon throughout, not ABS with carbon wrap. Consistent with Audi Sport RS5 Competition carbon exterior specification.
• UV-Resistant Finish: Double-layer UV-protective clear coat (CF) or UV-stable gloss black surface (FRP) — both resist fading and surface hazing over time on the B9 Coupe's exposed trunk spoiler surface.
• Tape-On, No Drilling: Double-sided adhesive tape included — no drilling, no modification to the factory trunk lid. Clean swap installation.

Note: Fits 2017–2023 Audi A5 S-Line, S5, and RS5 B9/B9.5 Coupe (2-Door) only. Not confirmed for A5/S5/RS5 Sportback (different trunk lid geometry). Tape-on installation, no drilling required.
