BMW F90 M5 Build Project – Carbon Fiber Aero Upgrade Overview

The BMW F90 M5 is already a powerhouse, but adding a full carbon fiber aero kit completely transforms its presence. This build features four key upgrades: a carbon fiber front lip, carbon fiber side skirts, carbon fiber rear diffuser, and a carbon fiber trunk spoiler. Together, these components create an aggressive, balanced, and OEM+ appearance.

Carbon Fiber Front Lip

The carbon fiber front lip sharpens the front end, adds width, and gives the M5 a lower stance. It enhances airflow and pairs perfectly with gloss-black grilles and trim.

Carbon Fiber Side Skirts

Carbon fiber side skirts extend the body line from front to rear and visually lower the vehicle. They help tie the aero kit together for a cleaner, more streamlined silhouette.

Carbon Fiber Rear Diffuser

The carbon fiber rear diffuser is one of the most dramatic changes, adding depth and aggression around the exhaust area. It improves airflow and delivers a true motorsport-inspired appearance.

Carbon Fiber Trunk Spoiler

The carbon fiber trunk spoiler is the perfect finishing touch. It enhances the rear profile, adds subtle downforce, and completes the carbon fiber theme front-to-back.

Final Result

With all four components installed, the F90 M5 gains:

• A wider, lower, more aggressive stance
• Full carbon fiber accents across the entire exterior
• An OEM+ look with supercar-level presence
• A cohesive and balanced aero design

This full carbon fiber kit elevates the F90 M5 visually and aerodynamically, giving it the sharp, dominant appearance it deserves. For help choosing the right aero parts, feel free to contact us.
