Mercedes Benz W205 C63/C63s AMG Sedan Carbon Fibre Rear Bumper LED Diffuser Kit

The most aggressive rear end available for the C63. Built for the C63 Sedan, this Carbon Fibre Rear Bumper LED Diffuser Kit transforms the back of the car with a multi-piece aero package - a carbon rear diffuser with an integrated centre LED light, an extended undertray with deep vertical fins, and matching side splitters.

Built for show and track presence, the kit extends well below and behind the factory bumper for a race-car profile. Finished in a high-gloss clear coat over a twill weave.
