Mercedes-Benz AMG C63 W205 (2014-2021) Prepreg Dry Carbon Fiber LED Rear Diffuser

Engineered for Mercedes-AMG C63 W205 (2014-2021) owners, this Prepreg Dry Carbon Fiber LED Rear Diffuser combines aggressive race aesthetics with an integrated LED brake/fog light. Manufactured in Europe and quality-controlled by BYC Performance, this Mercedes C63 LED carbon rear diffuser bolts directly to OEM mounting points and wires easily to standard 12V circuits.

Unlike the standard non-LED diffuser, this version features an integrated F1-style red LED module in the center channel. The LED can be wired as a brake light, fog lamp, or position lamp — adding a distinct night-time signature to the rear. The IP67-rated waterproof module operates reliably in all weather conditions.

Key Features

• Integrated LED Module: F1-inspired red LED — wired as brake, fog, or position lamp. IP67 waterproof, 12V DC.
• Prepreg Dry Carbon Technology: Autoclave cured under high heat and pressure for a more consistent weave.

• Direct OEM Fit: Bolts to C63 W205 / C205 (2014-2021) rear bumper points.
• Easy Wiring: Positive (red) and negative (black) leads splice to existing brake/fog wiring.
• 2x2 Twill Carbon Weave: Authentic pattern under high-gloss UV-protective clear coat.
• UV & Chemical Protection: Long-life fade resistance.
