Mercedes Benz W205 C63/C63s AMG Carbon Fibre OTM Style Rear Diffuser

Finish the rear of the C63 with this OTM Style Carbon Fibre Rear Diffuser. It replaces the factory lower diffuser section with a carbon piece that frames the AMG quad exhaust outlets and adds three vertical aero fins across the centre.
