BMW G30 3D Style Carbon Fiber Rear Diffuser

RW Carbon has released this 3D Style Carbon Fiber Diffuser for customers looking for something more aggressive and unique than the standard EC diffuser. Featuring extended side fins that flow toward the rear wheel wells, this diffuser creates a more dramatic motorsport-inspired appearance while helping complete a full carbon fiber ground effects setup.

The 3D Style design is especially ideal when paired with side skirt extensions, creating a seamless and aggressive lower-body profile. Constructed from genuine 2x2 carbon fiber, this one-piece diffuser is handcrafted to perfectly match other RW Carbon products for a consistent OEM+ finish.

Unlike some diffuser options, this piece installs directly over the OEM diffuser using screws and 3M tape, meaning the rear bumper does not need to be removed for installation.
