Rear Diffusers

A rear diffuser is the key to having a uniquely modified car.  It adds the much needed aggressive styling to the rear of your vehicle.  RW Carbon carries a HUGE selection of diffusers for BMW, Audi, Mercedes and Tesla!  Some of the diffusers we carry are available in carbon fiber or polypropylene.  Either choice is perfect for any auto enthusiast. Polypropylene can be prepped and painted, while a carbon fiber diffuser should be left raw.  Each one is professionally crafted to ensure the best fitment and durability.  A CF Diffuser comes with a thick clear coat for a beautiful shine.  We quality control every carbon fiber diffuser to ensure it is a great product before it is shipped out.
