Upgrade the rear-end appearance of your BMW G80 M3 and G82/G83 M4 with the AlpineX Dynamics V Style Pre-preg Dry Carbon Fiber Rear Diffuser.
Featuring a bold and motorsport-inspired design, this carbon fiber rear diffuser gives the BMW G8X M3 and M4 a lower, wider, and more aggressive rear-end appearance. The sculpted V Style profile adds greater depth and definition around the lower bumper and exhaust outlet area, creating a sharper and more performance-focused exterior finish.
Constructed from high-quality pre-preg dry carbon fiber with an authentic 2x2 weave pattern, each BMW G8X rear diffuser combines lightweight construction with excellent durability. The premium high-gloss UV-protected clear coat enhances the depth and visibility of the carbon weave while helping protect against fading, yellowing, and discoloration caused by sunlight and everyday environmental exposure.
Designed specifically for the factory BMW G8X M3 and M4 rear bumper, this V Style diffuser follows the original bumper contours for accurate alignment and integrated fitment. It is an ideal exterior upgrade for enthusiasts looking to complete a coordinated carbon fiber aero package or give their vehicle a more aggressive street, show, or track-inspired rear profile.

Construction & Design
Manufactured from premium 2x2 weave pre-preg dry carbon fiber, the AlpineX Dynamics V Style Rear Diffuser combines lightweight construction with a bold motorsport-inspired appearance.
The visible carbon weave provides a premium finish, while the high-gloss clear coat adds depth and helps protect the surface from UV exposure and everyday driving conditions. Its sculpted fins and pronounced lower profile visually widen the rear of the vehicle while creating a more aggressive appearance around the factory exhaust outlets.
The diffuser is shaped to follow the factory G8X M3/M4 rear bumper contours, maintaining a clean and cohesive installation while adding greater definition to the rear end.
Installation
Professional installation is strongly recommended to ensure proper alignment and secure mounting.
Test fitting is required before final installation. Removal of the factory rear diffuser may be necessary. Drilling, trimming, or additional mounting hardware may be required depending on the vehicle and installation method. Installation hardware is included unless otherwise stated.
