This CS style carbon fiber rear diffuser is for the 2017-2020 5-Series with the M Sport package, which includes the 530i, 530e, 540i, and M550i. This CS Style Diffuser is made using genuine carbon fiber and will perfectly match any other G30 RW Carbon Fiber parts and/or accessories. Always encased in a protective clear coat, you can expect this part to stand the test of time. This diffuser requires the removal of the rear bumper for installation so we highly recommend that you have either us at RW Carbon install it or another professional shop. Take your G30 from stock to extraordinary in a matter of a couple of hours with a new RW CS Style Carbon Fiber Diffuser. Please feel free to contact us if you have any further questions.
Installation
RW Carbon requests that you must get this CS style CF diffuser installed by a professional. The diffuser does require the entire rear bumper to be removed and screws inserted into the diffuser tabs. For further information feel free to email us at info@rwcarbon.com.
