2013–2016 Audi A3 / S3 / RS3 8V Sportback Rear Bumper Diffuser – Carbon Fiber

Enhance the rear styling of your Audi A3, S3, or RS3 8V Sportback with this carbon fiber rear bumper diffuser. Precision-molded to follow the factory bumper contours, it creates a lower, wider visual stance for a sharper, more performance-inspired rear end while keeping the clean lines of the original design.

Build

• Material: Genuine carbon fiber with an exposed weave, lightweight and durable
• Surface finish: High-gloss polished UV-resistant clear coat that showcases the carbon weave and protects it against fading and long-term surface degradation
• Configuration: Single-piece diffuser for the lower rear bumper

Design & Aerodynamics

• Aggressive stance: Diffuser profile creates a lower, wider visual stance for a sportier rear end
• Carbon aesthetic: Exposed weave and high-gloss polished finish deliver a motorsport-inspired look that complements the factory 8V design language
• Factory-style integration: Precision-molded to the contours of the factory rear bumper for a clean, seamless fit

Package Contents

• 1 × carbon fiber rear bumper diffuser
• Installation hardware

Installation

• Screw and adhesive mounted: Secures using both mounting screws and adhesive for a rigid, long-lasting fit
• Drilling required: Screw fixing pierces the bumper, so this is a permanent modification rather than a reversible fit
• Surface prep: Thoroughly clean, degrease, and dry the rear bumper before installation to ensure maximum adhesion and correct panel seating
• Alignment: Dry-fit and check the diffuser sits centred and even across the bumper before driving any screws
• Professional installation recommended for correct positioning, panel alignment, and a clean finish

Before You Install

• This is a permanent, screw-mounted fitment — confirm placement carefully before driving any screws, as holes cannot be undone
• Confirm your car is an 8V Sportback before ordering — this will not fit the Sedan or the later 8Y generation
• Verify your rear bumper shape against the product images before ordering — bumper detailing differs between trim levels
• Take care when parking rear-in — lower rear panels sit close to kerbs and parking blocks
