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

Take the C63's rear aero to the next level with this P Style Carbon Fibre Rear Diffuser. A large add-on diffuser that mounts beneath the rear bumper, it extends under the car with four tall vertical strakes for a purposeful, race-bred look.

It works with the factory rear bumper and exhaust outlets, adding depth and aggression without replacing any original panels. Finished in a high-gloss clear coat over a twill weave.
