Carbon fiber parts still require prep work. You will need to preform taks such as: buffing, drilling holes (for winshield windshield water nozzles, etc), adding or removing fiberglass (mounting tabs, etc). Ships direct from the manufacturer or a distributor. Manufactured with a marine gelcoat variant to help prolong the life against UV aging effects.

Why choose AeroFunction body kits for your BMW M3

Aero Function delivers performance-focused body kits engineered to sharpen both the look and aerodynamic efficiency of your BMW M3. With years of experience developing components for high-end vehicles, their designs bring a bold, sculpted presence while maintaining functional integrity on the road.

Each Aero Function kit for BMW M3 is produced using carefully selected materials. GFK (Glass Fibre Komposite) offers a balance of strength and adaptability, CFP (Carbon Fibre Plastic) provides lightweight performance with UV resistance, and Pur Rim (Polyurethane Plastic) delivers flexibility with impact resistance. All components are manufactured in-house to ensure consistent quality and attention to detail.

Installation of GFK components may require minor adjustments to achieve ideal fitment. It is recommended to test fit all parts before final installation. In some cases, trimming or additional fiberglass work may be needed to perfect alignment. Taking these steps ensures your BMW M3 achieves a clean, professional finish with enhanced styling and performance.

Disclaimer:

Aero Function diffusers are aftermarket aerodynamic accessories designed specifically for enhancing style and performance. These diffusers are not “direct bolt-on” parts and may require significant preparation, such as sanding, fitting, or custom bodywork. Common installation challenges can include potential warping, cracking, or fitment issues if the diffuser is not handled or installed correctly.

Aero Function diffusers are generally installed below the rear bumper, and in many cases, the bumper may need to be modified to ensure a proper fit. It’s important to select a diffuser that is compatible with specific bumpers, trims, or aftermarket styles to avoid fitment issues.

Separate mounting hardware, such as L-brackets, bolts, screws, washers, and fasteners, is typically required but not included in the package. L-brackets help attach the diffuser securely to the vehicle’s chassis or bumper, while additional supports may be needed depending on the design and fitment. Installers will need to source the necessary materials separately to ensure compatibility with both the diffuser and the vehicle.

For the best results, Aero Function recommends professional installation by a custom shop experienced in aftermarket accessories. Many standard auto repair shops may lack the expertise to handle the specific fitment and hardware requirements for these diffusers.

Please note that these diffusers are intended strictly for off-road and show use. Due to strict Department of Transportation (DOT) regulations, most Aero Function diffusers are not street-legal. Aero Function does not endorse or recommend using these diffusers on public roads or highways.
