RW Carbon has released this 3D style carbon fiber diffuser for those customers that might want something more aggressive and unique looking than our EC diffuser. This 3D Style carbon fiber rear diffuser is more aggressive than the EC style due to its side fins that extend to the back of the rear wheel wells. This a great feature if you want to run some of our side skirt extensions as it will help to create that complete carbon fiber ground effect. This diffuser is a one piece design and features a simple bolt on installation. These diffusers will fit all 2017-2020 BMW G30 5 series models with the M Sport package. That includes the 530i, 530e, 540i and the M550. This product is handcrafted using genuine carbon fiber in a 2x2 weave pattern to ensure it matches with other RW Carbon products. Please reach out if you have any questions about this G30 3D style diffuser.
Installation
Although installation for this BMW G30 M Sport 3D diffuser is fairly simple, RW Carbon still urges that you use professional help to get this piece installed. It will require using screws and 3M tape and will mount over the OEM diffuser so the bumper does not need to be removed. If you live near RW please reach out and we can set up an installation appointment.
