C3 Carbon BMW F82 M4 Carbon Fiber Rear Diffuser
Beautiful carbon fiber rear underbody diffuser from C3 Carbon! This is among the coolest carbon upgrades you can make to your M4. Made from 100% dry carbon fiber, autoclaved in custom billet aluminum molds and hand-finished using premium automotive clear urethane, this rear diffuser has the look, quality, and fitment that makes it absolutely indistinguishable from factory pieces -- if the factory would even offer one! A diffuser works by smoothing the airflow exiting from beneath your car, reducing turbulence behind the vehicle that causes drag.

Experience the Difference of C3 Carbon Products:
Competition Carbon Components (C3 Carbon) has been steadily gaining in popularity amongst today’s high-performance driving enthusiasts due to several key factors that help C3 Carbon stand out in a market full of sub-par aftermarket offerings. Each C3 Carbon product is manufactured to provide perfect fit and extreme strength while reducing weight, maximizing quality and ensuring years of exceptional finish. We provide all of this for significantly less money than OEM parts.
Every product we make uses pre-impregnated dry carbon formed in a CNC-machined billet aluminum mold which is manufactured by laser-scanning the OEM component(s) so you know you’ll have a perfect fit, every time. Dry carbon is stronger and lighter than wet carbon, often weighing 1/3 of our competitors’ products. Our manufacturing methods also produce a smoother surface on each part for more dimensional accuracy; shaving edges, widening mounting holes and flexing pieces to make them fit are a thing of the past.
C3 Carbon also applies an automotive urethane clear-coat which is U/V cured for durability and guarantees C3 Carbon parts won't yellow over time.
Many of our competitors use wet carbon (which is heavier), and some use fiberglass with a carbon overlay (much heavier, as the carbon fiber has epoxy literally painted onto it). These materials and manufacturing methods produce a poor finish due to air contamination, and because the epoxy isn’t applied uniformly throughout the weave. These products are also much weaker than C3 Carbon products. Finally, most competitors use a fiberglass mold, which is far less expensive but cannot maintain the strict tolerances we demand of our own products. In the end, the fit and finish simply cannot stand up to C3 Carbon products.
