Upgrade the exterior styling on your G80/G82 with our In-House designed and engineered ABS Rear Diffuser. Utilizing factory mounting locations and supplied hardware this diffuser is a direct bolt-on upgrade that can be installed directly in place of your factory diffuser. Featuring a deep profile, an aggressive fin design, and extending the entire width of the rear bumper, our exclusive design is sure to turn heads! Our engineers did an absolutely amazing job on this diffuser from the styling to the fit and finish that is guaranteed to stand out in the market.

Pay close attention to the design characteristics of the diffuser.

This allows daily drivability to be largely unaffected and the improved look be enjoyed free of worry.

The Alpha N hood for the BMW G8X M3 and M4 is made entirely of carbon fiber with an additional layer Kevlar on the inside, which serves the stability. Taking some queues from the M4 GT3 race car, this vented carbon hood weighs 40% less than the original. While BMW utilized aluminum to keep the factory hood as light as reasonably possible for a production car, the Alpha N hood comes in at only 17lbs vs the 28lbs of the OE hood. Paint/clear coat required for installation

Alpha-N has a reputation for pushing the boundaries of performance and style. With Alpha-N's connection to BMW Motorsport and their track record of producing high-quality carbon parts, their latest G8X M2 / M3 / M4 components are no exception. Anyone familiar with Alpha's carbon fenders for the latest G87-chassis M2 knows that their aero components are truly an exercise of form following function. As aero designs advance and motorsport applications make their way onto road cars, we once again see that Alpha-N is employing a proper functional design for airflow around the front of the car. Similar to their G87 fender set, Alpha's G82 M4 carbon fender set utilize similar upper fender louvers as well as side vent elements. As air flows into the left and right coolers in the M4's front bumper and into the wheel wells, it can then escape out of the front fender louvers as well as the side vents in front of the doors. The mass evacuation of air from inside the front fenders reduces air pressure, increasing downforce. Fender set construction is full pre-preg carbon fiber in a 4x4 weave with 2x2 upper vents. The Alpha-N G82 M4 Carbon Fender Set is as lightweight, stylish, and functional as they come; if you’re in the market for a fender set, there’s no better part. NOTE: FENDERS COME IN RAW CARBON FINISH.

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
