About the BMW M5 3D style carbon fiber rear diffuser:
The PhaseCarbon BMW M5 3D style carbon fiber rear diffuser was designed specifically for the F10 generation BMW M5 super sedans.
With quality and fitment in mind, we wanted to bring only the best to our fellow enthusiasts, so if you've been considering this upgrade but something held you back from pulling the trigger, we believe we have the answer for you.
When you shop with us, you can buy with confidence that you will be getting a top notch product backed by incredible customer service and a money back guaranty.
We stand behind our manufacturer, our products, and our QC process to ensure that you are getting a spectacular hand-made product that looks great and fits great.
NOTE: If you have the M Sport rear bumper of one of our PhaseOne rear bumpers on any of the other F10 BMW 5 series (non M5), you can also replace the rear diffuser with this one. You will however need to modify your exhaust to accommodate the quad setup.
DIY Note: It is highly recommended that the rear bumper be removed for the easiest installation and the best fitment. If you have not worked with carbon fiber before, we highly recommend bringing your vehicle to a professional. We will not be responsible for any damage that occurs during self-installation.
