2010–2015 Audi R8 V8 / V10 Coupe Type 42 Rear Bumper Diffuser – Carbon Fiber

Transform the rear profile of your first-generation Audi R8 V8 or V10 Coupe with this carbon fiber rear bumper diffuser. A direct-fit retrofit for the factory rear bumper, this diffuser sharpens the lower rear end — visually widening and lowering the rear stance for a more aggressive, motorsport-inspired presence with a genuine carbon weave finish.

Build

• Material: Genuine carbon fiber, autoclave cured using a 3D design and CNC moulding process for consistent resin distribution and a tight, uniform weave
• Surface finish: High-gloss epoxy-polished top coat that holds its deep carbon appearance through sustained outdoor and driving exposure without fading or yellowing
• Configuration: Single-piece diffuser for the lower rear bumper
• Weight: Approximately 6.3 kg

Design & Aerodynamics

• Aggressive stance: Diffuser profile visually widens and lowers the rear stance for a more track-inspired rear-end presence
• Carbon aesthetic: Directional weave and gloss finish complement the R8's factory bodywork 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

• 2010–2015 Audi R8 V8 Coupe (first generation, Type 42)
• 2010–2015 Audi R8 V10 Coupe (first generation, Type 42)
• Body style: Coupe (2-door) only
• Fits the factory rear bumper only — not compatible with aftermarket configurations
• Not compatible with the second-generation R8 (Type 4S, 2016+) or the Spyder

Package Contents

• 1 × carbon fiber rear bumper diffuser
• Adhesive tape for installation
• Mounting screws for installation

Installation

• Tape and screw mounted: Secures with both the included adhesive tape and mounting screws for a secure, long-lasting fit suited to sustained driving
• Surface prep: Thoroughly clean, degrease, and dry the rear bumper at the diffuser position before fitting to ensure maximum adhesion
• Alignment: Ensure the diffuser is centered and symmetrical across the rear bumper before final installation
• Professional installation recommended for correct positioning, panel-gap consistency, and finish

Before You Install

• This diffuser uses screws in addition to adhesive tape — installation involves hardware mounting, so confirm placement before securing
• Confirm your R8 is a first-generation Coupe (2010–2015, Type 42) before ordering
• Verify body style and generation using your model year and chassis code if you are unsure
