Due to material property of carbon fiber, it is required to remove the rear bumper of your F30, F32, F80, F82 BMW before rear diffuser can be installed; and the reason is that carbon fiber is not flexible like OEM plastic (PU) material.
Once the diffuser is properly fitted onto OEM rear bumper, fasteners should be installed on each tabs of the diffuser, and apply adhesive to each tabs for stronger hold.
