This 3D styled carbon fiber rear diffuser is our most aggressively styled diffuser for the F85 X5M. These will fit all 2015-2018 BMW F85 X5M and models. This diffuser will not only give the exhaust tip area a new aggressive look, but it will also follow the sides of the rear bumper to give you a lower and more race inspired feel. If you have a side of our side skirt extensions it will really complete the side profile appearance of your X5M. This diffuser is made using RW Carbon's 2x2 weave carbon fiber fabric, so it will match other RW parts and accessories. Be one of the first in your town to rock this 3D style rear diffuser and pick up yours today. Each diffuser we sell is quality checked in house before we ship them across the globe.
