A carbon fiber rear diffuser for your F30 might be one of the most under rated modifications. The F30 has a fairly small diffuser so it can go unnoticed. However, the bland looking grey diffuser from the factory just doesn’t cut it when compared to our performance style carbon fiber diffuser from RW Carbon. This diffuser fits 328i, 330i, 335i, and 340i F30 3 Series M Sport models. It is made out of REAL carbon fiber and is hand crafted to ensure a perfect ratio of carbon fabric and resin. This precise mixtures ensures optimal strength to weight ratio. Once the rear diffuser is molded it is then sprayed with a thick clear coat which gives it that deep show like shine while protecting the piece from road debris and UV rays. Stop waiting around and get your own Performance Style Carbon Fiber F30 Rear Diffuser today and see the world of difference it will make on your 3 series.
