TTRS Carbon Diffuser – AP Design Rear Diffuser for Audi 8S Pre-Facelift

▪️Audi TTRS 8S Pre-Facelift (2017–2018)

Aggressive Rear-End Styling for the TTRS 8S Pre-Facelift

Give your Audi’s rear end a race-inspired transformation with the TTRS Carbon Diffuser by AP Design. Designed specifically for the TTRS 8S Pre-Facelift (2017–2018), this carbon fibre rear diffuser delivers a sharp, aggressive look while enhancing airflow and downforce.

Whether you're building a show car or preparing for spirited driving, this diffuser checks all the boxes—style, fitment, and function.

Designed with Performance and Fitment in Mind

Crafted using 100% pre-preg dry carbon fibre, the AP Design diffuser features a 2x2 twill weave and a premium gloss clear coat that resists UV rays and fading. Because it's tailored specifically for the OEM bumper, the fitment is precise and secure without needing any modifications.

Installation can be completed with existing mounting points and basic tools—no cutting, drilling, or trimming required. You’ll maintain full compatibility with parking sensors and factory exhaust configurations.

Key Features:

• Made from dry carbon fibre – 2x2 twill weave
• AP Design – lightweight, rigid, and aggressive
• Gloss clear coat finish with UV protection
• Compatible with OEM parking sensors & exhausts

To complete the rear transformation, pair this diffuser with our TTRS 8S Carbon Side Skirts or Carbon Rear Spoiler Extension for a full AP Design package.

Form Meets Function

The TTRS carbon diffuser isn’t just for looks—it also helps manage underbody airflow by channeling turbulence and improving rear-end stability. In turn, this contributes to a more planted feel at speed, particularly when combined with other aerodynamic upgrades.
