2015–2016 Audi S3 8V Sedan RS Style Rear Bumper Diffuser – Carbon Fiber

Enhance the rear profile of your Audi S3 8V Sedan with this carbon fiber rear bumper diffuser. Finished in a high-gloss 3K twill weave, the RS-style profile delivers a more aggressive, performance-oriented rear appearance that complements the factory body lines without permanent modification.

Build

• Material: Genuine carbon fiber in a 3K twill weave — strong and durable with an authentic weave appearance over carbon-look ABS alternatives
• Surface finish: High-gloss epoxy coating with UV protection that showcases the natural carbon weave and resists fading, yellowing, and surface degradation through prolonged outdoor and driving exposure
• Configuration: Single-piece diffuser for the lower rear bumper
• Panel width & weight: 143 cm across · approximately 5 kg

Design & Aerodynamics

• RS-style profile: Diffuser shape brings a more aggressive, performance-oriented look to the S3 rear bumper
• Carbon aesthetic: 3K twill weave and high-gloss finish complement the factory bodywork for a coordinated, motorsport-grade look
• Factory-style integration: Precision-molded to follow the contours of the factory rear bumper for a clean fit

Installation

• Direct retrofit: Fits the factory rear bumper with no cutting or permanent bodywork modification required
• Surface prep: Thoroughly clean and degrease the rear bumper before installation to ensure correct panel seating
• Alignment: Dry-fit and check the diffuser sits centred and even across the bumper, with consistent gaps on both sides, before final fitting
• Professional installation recommended for correct panel alignment and finish quality

Before You Install

• Mounting hardware is not included — source any required fixings or adhesive ahead of installation
• Confirm your car is an S3 8V Sedan before ordering — this will not fit the standard A3, the RS3, or the later 8Y generation
• This is a substantial panel — plan for a second pair of hands during fitting
• Take care when parking rear-in — lower rear panels sit close to kerbs and parking blocks
