Deep Carbon Rear Valance Styling to Sharpen the Audi RS3 8V LCI Exhaust Profile
Designed for the Audi RS3 8V LCI Sedan (2017–2020), this carbon fiber rear diffuser replaces the factory lower rear valance with a deeper and more aggressive performance-inspired design. The vehicle-specific profile follows the RS3 rear bumper contours while adding pronounced diffuser fins and sculpted outer sections around the signature oval exhaust outlets for a cleaner OEM+ appearance.
Made from real carbon fiber with a 3x3 twill carbon fiber weave, UV-protected clear coating and a shiny gloss carbon finish, the rear diffuser delivers a lightweight exterior upgrade with a premium visible carbon appearance. Its deeper centre section adds definition across the lower bumper and complements carbon fiber side skirts, spoilers and other Audi RS3 8V LCI exterior upgrades.
The vehicle-specific replacement design is shaped around the factory RS3 Sedan rear bumper for clean integration and accurate positioning. Professional installation is recommended for precise alignment, exhaust clearance, secure mounting and long-term durability.
