SQ-Aero Pre-preg Carbon V1 Diffuser – Audi RS3 8Y.5 (2025–Up)
Compatible with both Sportback and Sedan models
Engineered for the facelifted 2025-Up Audi RS3 8Y.5, the SQ-Aero Pre-preg Carbon V1 Diffuser delivers a significant aerodynamic and visual upgrade, bringing true motorsport aggression to the rear section of the RS3.
This three-piece system includes:
- 1 × Center Diffuser
- 2 × Side Diffuser Trims
Designed together as a complete aero assembly to optimize airflow extraction, improve high-speed stability, and dramatically sharpen the rear profile.
Each component is constructed from authentic pre-preg (dry) carbon fiber, vacuum-bagged and autoclave-cured to achieve superior structural rigidity, reduced weight, and exceptional weave consistency. This manufacturing method produces a tighter carbon matrix and greater impact resistance under heat cycling and aerodynamic load—far exceeding the performance of traditional wet-lay carbon.
The V1 variant features an aggressive, performance-forward geometry with deeper fins and more pronounced venting, engineered to enhance airflow evacuation from beneath the chassis. CAD-developed specifically for both the 8Y.5 Sportback and Sedan, it ensures precise OEM-grade fitment for each body style.
Finished in a UV-stable, high-clarity gloss clear coat over a 2x2 twill weave, the diffuser integrates cleanly with other SQ-Aero and OEM carbon components, forming a cohesive motorsport aesthetic.
