Give your BMW the super-aggressive appearance it deserves with our PSM style diffuser set. Monaco Motorsports is proud to present this piece made of 100% pure hand made carbon fiber material. The advantages of this product being made of purely carbon fiber features lighter weight and a stronger structure. We take pride in our 100% carbon fiber products for they take special attention to detail for durability made to last. This set is handmade to ensure fitment all around with the highest quality material.

All of our products are coated with UV protectant clear coat. Normally parts are produced with fiberglass as base and a carbon fiber layer, although this is a market standard nothing beats the confidence of a pure carbon fiber structure presented in this product. We urge you to ask our competitors the components of their carbon fiber products in making your decision (you may come to find many competitors advertise their parts being carbon fiber without mentioning the fiberglass structure underneath).  

Carbon fiber is lighter and stiffer than fiberglass, this is the reason performance racing parts are manufactured with carbon fiber. Stand out from the crowd by adding this piece onto your BMW for higher performance and improved aesthetics. This diffuser will undoubtedly create a bold and aggressive look to your M3 or M4 by making it a show stopper. This set is a great addition to any M3 or M4. Feel free to ask any questions about this product and how our products match up with our competitors.
