Mercedes-Benz W205 C63 AMG Coupe Carbon Fiber Rear Diffuser (2015-2019): Hand-Laid Carbon Weave Replacement

It replaces the plain lower valance on the Mercedes Benz W205 C63 AMG Coupe (2015 2019): Hand Laid Carbon Weave Replacement with a finned diffuser that cleans up the airflow leaving the rear bumper.

Carbon fiber – not a hydro-dipped or printed film. You can see the weave shift as the light moves across the surface.

Undo the lower bumper fixings, offer the diffuser up, and re-use the original screws where the holes align – about an hour.

Fits: Mercedes Benz W205 C63 AMG Coupe (2015 2019): Hand Laid Carbon Weave Replacement

Moulded from the Mercedes Benz W205 C63 AMG rear bumper profile so the outer edges meet the bumper corners cleanly.

Quad-exit and single-exit cars use different cut-outs – confirm from the listing photos which bumper your car has.

Weave, finish and edge treatment are all chosen when you order: glossy 3K twill is the default, while matte, forged carbon, coloured clear coat and carbon-kevlar hybrids are produced on request.

• Logo application or badge cut-outs on request
• Gloss, matte, satin or forged carbon finish
• 3K twill, 6K twill, plain weave or carbon-kevlar hybrid
• Coloured tinted clear coat (red, blue, yellow)

Wash with a soft mitt and a pH-neutral shampoo, and avoid abrasive polishes or machine compounds that cut through the clear coat.

Quality control is a visual inspection plus a fit check on the master jig; anything with a lifted clear coat or a distorted mounting edge is rejected rather than shipped and discounted.

Our plant runs autoclave curing with logged temperature and pressure curves, so if a part ever fails we can trace the batch it came from.

For bulk orders we quote from your drawing, scan or sample part; new tooling usually takes 15-25 days, then each batch runs in 20-35 days depending on quantity.

Allow 10-15 business days for production plus transit time; express DHL, UPS and FedEx options are available at checkout, and the part carries a 12-month warranty against manufacturing defects.

In the box: diffuser, screws, clips and a fitment card.
