Mercedes-AMG C63 C63 S Carbon Fiber Rear Bumper Diffuser

Upgrade the rear-end appearance of your Mercedes-AMG C63 or C63 S Coupe / Convertible with this one-piece carbon fiber rear bumper diffuser. Designed for selected two-door C63 models, this rear diffuser gives the rear bumper a sharper, lower and more aggressive AMG-style look.

This product is a rear bumper diffuser, not a full rear bumper, rear bumper splitter set or complete body kit. Please confirm your rear bumper style before ordering. If you are unsure about fitment, send us your vehicle year, model and rear bumper photos through our Contact Us page.
