2017–2024 Audi RS4 B9 Avant Single Deck Rear Window Wing Spoiler – Dry Carbon Fiber

2017–2024 Audi RS4 B9 Avant Single Deck Rear Window Wing Spoiler – Dry Carbon Fiber

Transform the roofline and rear window profile of your Audi RS4 B9 Avant with this dry carbon fiber rear window wing spoiler. Mounted at the rear window surround in a single-deck profile, it adds a bold, performance-inspired detail to the roofline with a high-polish 3K twill carbon finish.

Build

• Material: Autoclave dry carbon fiber in a 3K twill weave — the resin is pre-impregnated into the weave before autoclave curing, giving more consistent resin distribution, a tighter weave pattern, greater structural rigidity, and a lighter finished component than standard wet carbon
• Manufacturing: 3D design and CNC moulding with autoclave dry carbon curing
• Surface finish: High-polish gloss black finish that showcases the natural 3K twill weave with strong UV and moisture resistance through long-term outdoor and driving exposure
• Panel width: 165 cm across for a fully proportioned rear window spoiler presence

Design & Finish

• Roofline profile: Single-deck wing at the rear window surround creates a bold, motorsport-inspired roofline silhouette
• Carbon aesthetic: Refined 3K twill dry carbon weave and gloss finish complement the factory RS4 Avant bodywork for a coordinated, motorsport-grade look
• Factory-style integration: Precision-molded to follow the contours of the factory roofline and rear window surround for a clean, seamless fit

Fitment

• 2017–2024 Audi RS4 B9 Avant (2.9 Quattro)
• Fits the RS4 B9 Avant factory roofline and rear window surround only — not compatible with aftermarket configurations
• Body style: Avant only — does not fit Sedan or Allroad body styles

Package Contents

• 1 × dry carbon fiber rear window wing spoiler
• 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 roofline or rear window surround
• Surface prep: Thoroughly clean, degrease, and dry the roofline and rear window surround before fitting to ensure maximum adhesion
• Alignment: Dry-fit and check the spoiler sits centred and symmetrical across the roofline before final adhesion
• Professional installation strongly recommended — a panel of this width requires careful positioning to achieve symmetrical alignment and a clean finish

Before You Install

• Confirm your car is an RS4 B9 Avant (2017–2024) before ordering — this will not fit the Sedan or Allroad
• Adhesion at the roofline depends on good surface prep — work in moderate temperatures and allow the tape to cure fully before washing the car
• Measure from fixed reference points on both sides before adhesion; a 165 cm panel shows even small asymmetry clearly
• Installation is reversible, but adhesive removal and re-prep may be required if the spoiler needs repositioning
