Mercedes-Benz C63 (2015-2021) - Carbon Fiber Rear Diffuser

Transform the rear-end presence of your Mercedes-AMG C63 or C63 S (2015–2021) with our Carbon Fiber Rear Diffuser — an aggressive, track-inspired upgrade built to deliver both exotic styling and aerodynamic performance. With sharp fins, sculpted lines, and a bold stance, this diffuser enhances airflow while bringing motorsport aggression to the rear bumper.

Crafted from 100% authentic 3K twill weave carbon fiber, this diffuser offers the perfect balance of ultra-lightweight construction and structural rigidity. The multi-fin design adds depth and sharpness, visually lowering the car while optimizing underbody airflow for improved high-speed stability.

Finished in a deep-gloss UV-resistant clear coat, the carbon fiber stays rich and reflective while resisting fading, yellowing, and damage from road debris and heat — built to look just as aggressive up close as it does from a distance.

Designed for OEM-style fitment, this diffuser installs cleanly with factory mounting points and integrates seamlessly with your AMG’s stock or upgraded exhaust system.
