Carbon Fibre Rear Diffuser – Audi TTRS 8S FL 2020+ Aerodynamic Upgrade

Bold, Lightweight Performance for Your Audi TTRS 8S FL

If you’re looking to elevate the rear-end presence of your Audi TTRS 8S FL (2020+), this carbon fibre rear diffuser is a must-have. Designed for both form and function, it provides true aerodynamic gains while drastically enhancing visual appeal.

Because it is constructed from high-grade dry carbon or forged carbon fibre, this diffuser not only looks aggressive but also delivers measurable performance benefits. Moreover, its OEM-style fitment ensures quick installation with no modifications required.

Precision Fit for 2020+ TTRS 8S Facelift Models

Since this diffuser is specifically designed for facelifted TTRS 8S Coupes from 2020 onwards, you can expect a flawless fit. Additionally, it supports full functionality of your OEM sensors and cameras without interference.

✅ Fitment Includes:

• Audi TTRS 8S FL Coupe (2020+)

• Compatible with all OEM parking sensors and reverse cameras

• Works with RS-style and standard rear spoilers

Dry Carbon Fibre Construction for Lightweight Strength

Unlike conventional plastic diffusers, this version is crafted entirely from aerospace-grade carbon fibre. As a result, it offers unmatched strength, reduced weight, and long-term durability. Furthermore, the autoclave-cured pre-preg material resists yellowing, warping, and cracking — even under extreme conditions.

Material Highlights:

• 100% Pre-Preg Dry or Forged Carbon Fibre

• UV-protected gloss or matte finish

• Approx. 1 kg lighter than stock diffuser

• OEM-style 2×2 twill or forged weave patterns

Aerodynamic Performance, Engineered for Speed

Beyond aesthetics, this carbon fibre rear diffuser plays a vital role in airflow management. By directing airflow efficiently under the rear bumper, it helps reduce lift, increase stability, and promote downforce at higher speeds. Therefore, it’s not just about looks — it enhances driving dynamics as well.

Performance Benefits:

• Improved underbody airflow

• Increased rear-end downforce

• Reduced lift and drag at high speeds

• Ideal when paired with carbon side skirts and front splitters

Effortless Installation with OEM Mounts

Because it’s designed with direct factory replacement in mind, installation is straightforward and fully reversible. You don’t need to cut or modify any body panels. With just basic tools, the entire process takes around 1.5 hours.

Install Overview:

• Fully reversible

• Uses original mounting points

• Compatible with OEM hardware and clips

• Installation guides and videos available upon request

Pair It with Complementary Carbon Aero Parts

To get a consistent carbon aesthetic, you can combine this rear diffuser with other aerodynamic parts built from the same carbon weave. Doing so not only improves appearance but also maximizes aerodynamic synergy.

Recommended Add-Ons:

• Audi TTRS 8S FL Carbon Side Skirts

• TTRS 8S Carbon Front Splitter – 2020+ Fitment

• Audi Carbon Mirror Covers

• Dry Carbon Rear Spoiler Extensions for TTRS 8S FL
