2013–2016 Audi A7 S-Line C7 Sportback Rear Bumper Diffuser – Carbon Fiber

Transform the rear profile of your Audi A7 S-Line Sportback with this carbon fiber rear bumper diffuser. A direct-fit retrofit that replaces the factory lower rear valance, it sharpens the rear end with a bold, performance-focused carbon profile that visually widens the rear stance and builds on the A7's S-Line character.

Build

• Material: Genuine carbon fiber — lightweight, durable, and built to withstand long-term driving and outdoor exposure
• Surface finish: Gloss black polished finish that holds its deep carbon appearance and weave clarity without fading or yellowing under prolonged sun and weather exposure
• Configuration: Single-piece diffuser for the lower rear bumper
• Colour match: Gloss black carbon integrates cleanly with both light and dark factory paint colours

Design & Aerodynamics

• Aggressive stance: Diffuser profile visually lowers and widens the rear stance for a more track-inspired, performance-focused rear end
• Carbon aesthetic: Consistent directional weave and gloss finish complement the sporty contours of the A7 Sportback for a coordinated, motorsport-grade look
• Factory-style integration: Precision-molded to the contours of the factory rear bumper for a clean, seamless fit

Fitment

• 2013–2016 Audi A7 S-Line Sportback (C7, 4-door)
• Fits the A7 S-Line factory rear bumper only — not compatible with the standard non-S-Line A7 or aftermarket rear bumper configurations
• Body style: Sportback (4-door) only
• Confirm S-Line trim as well as model year before ordering

Package Contents

• 1 × carbon fiber rear bumper diffuser
• Protective carton packaging

Installation

• Bolt-on retrofit: Replaces the factory lower rear valance — no cutting or permanent bodywork modification required
• Surface prep: Thoroughly clean and degrease the rear bumper before installation for a secure, precise fit
• Alignment: Check that the diffuser sits centred and even across the rear bumper before final tightening
• Professional installation recommended for the best alignment, panel-gap consistency, and finish

Before You Install

• Confirm your car is an A7 S-Line Sportback (2013–2016) before ordering — this will not fit the standard non-S-Line A7
• Mounting hardware is not included — this is a bolt-on part, so source any required fasteners or clips ahead of installation
• Installation is reversible with correct technique, preserving the factory valance for future reinstallation
• Verify body style and trim using your model year if you are unsure
