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

They’re engineered to control airflow, helping reduce rear-end lift and improve stability at higher speeds without hurting daily drivability. Why it deserves a spot on your G90 M5: Pre-preg Carbon Fiber Construction – Lightweight, high-strength carbon fiber with a flawless gloss finish Factory-Accurate Fitment – 3D scanned for precise alignment with the OEM rear bumper CFD-Optimized Aerodynamics – Designed to reduce drag and enhance high-speed stability Track-Inspired Styling – Aggressive fins and crisp lines that elevate the rear profile Bottom line: whether you’re after real aerodynamic gains or simply want a more aggressive rear-end presence, the ADRO G90 M5 Rear Diffuser delivers both.

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.

Carbon fiber body parts are starting to become a dime-a-dozen, but this has caused a reduction in part quality. Vorsteiner takes great care to ensure every carbon fiber component they produce is of the highest quality, putting every piece through an independent inspection process to look for any potential imperfections before they leave the facility. In addition, the high gloss clear coating applied to their carbon fiber parts is a UV ray inhibiting coating that won't discolor or peel after only a few years of sun exposure. Looking to make your G8x M3 or M4 more unique? Then this may be the perfect option for you! Vorsteiner's VRS Aero Rear Diffuser is designed for those looking to add some flair and function to their vehicle. This diffuser is composed of durable Carbon Fiber material which comes in a glossy finish. In addition to being lighter and more aggressive looking, this diffuser also allows for an increase in downforce thanks to its design.
