Audi RS3 8Y LCI Pre-Preg Carbon Fibre Rear Diffuser by AP (2024+)

The RS3 8Y LCI already exits with intent — the Automotive Passion Pre-Preg Carbon Fibre Rear Diffuser makes sure it arrives the same way. Engineered specifically for the facelifted 8Y platform, this is a rear diffuser that earns its place both aesthetically and aerodynamically, replacing the factory unit with a piece that belongs on a car built to this standard.

Constructed from pre-impregnated carbon fibre and autoclave-cured for a finish that rivals the best in the industry, every diffuser leaves production with a flawless high-gloss 2×2 twill weave that reframes the entire rear end. Up close, the depth and clarity of the weave is immediately apparent — this is a material upgrade as much as it is a visual one.

Beyond the aesthetics, the diffuser's geometry is designed to manage underbody airflow at the rear of the car, reducing lift and adding stability at speed. For a car as capable as the RS3, that's not a small thing. It's the kind of detail that rewards the driver as much as the audience.

Fitment is direct and clean, designed as an OEM-quality replacement for the 8Y LCI rear bumper with no cutting or modification required. The result is a seamless integration that looks factory in its precision — just considerably lighter and significantly more purposeful.

Key Features:

• Pre-preg carbon fibre construction — autoclave cured for motorsport-grade quality
• High-gloss 2×2 twill weave with UV-protective lacquer
• Reduces rear lift and improves high-speed stability
