4RS B9 A5/S5 Carbon Fiber Vented Fenders

Key Features

Lightweight 3×3K Twill Carbon Construction
Multi-layer, hand-laid 3×3K twill carbon fiber using high-temperature epoxy resin delivers exceptional strength while significantly reducing weight compared to factory steel panels.

Integrated Functional Vents
Precision-designed louvers help extract heat from the engine bay and front wheel wells, improving airflow, cooling efficiency, and reducing front-end lift under load.

Direct Bolt-On Fitment
Engineered using OEM geometry for a true bolt-on installation. Mounting points align with factory tolerances and utilize original hardware—no cutting or modification required.

High-Gloss UV-Protected Finish
Finished in a deep, mirror-like UV-resistant clear coat to prevent fading or yellowing while showcasing consistent 4RS weave alignment throughout the panel.

Motorsport-Inspired Design
Aggressive surfacing and vent placement give the B9 A5/S5 a track-ready aesthetic while remaining fully street-drivable and OEM-plus in execution.
