Rather than replace the full diffuser and have potential fitment challenges with various exhaust options Dinan has opted to retain the factory gloss black lower portion of the diffuser and only replace the upper diffuser surround with a carbon fiber accent piece. This solution not only guarantees the carbon cosmetics will always play well with any personalization of the exhaust that is adopted but also offers an economical option compared to much pricier alternatives. Together with the Dinan Rear Side Splitters, the combination creates a "full" rear diffuser that is restrained but elevated and creates a nuanced OEM+ option for the marketplace. Features: 2x2 gloss twill dry carbon fiber (pre-preg) manufactured to be impact-resistant, durable, and strong Clear-coated for maximum UV protection and fade resistance Utilizes factory mounting tabs for an easy installation with a clean fit and finish Pair together with the Dinan Rear Side Splitters to complete the full rear look

Carbon fiber is a staple in the performance world and has been incorporated into motorsports since the early 80s. Over time companies have taken it upon themselves to create new carbon products to add to your car that may not have been originally available. Autotecknic is no different. If you're looking for a carbon addition that has been made to the highest standards with premium materials, then Autotecknic's line of carbon additions is your one-stop shop. Give your M5 a more aggressive appearance with this dry carbon fiber diffuser! This carbon fiber center diffuser comprises 100% pre-preg dry carbon technology for the ultimate lightweight, high-durability, and precise fitment. Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed autoclave to cure properly. This method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced.
