The SQ-Aero Dry Carbon Fiber Rear Diffuser was developed to complement the coupe-inspired proportions and athletic character of the BMW G02 X4 LCI. Designed to integrate seamlessly with the factory rear bumper, the diffuser adds greater visual depth and definition while maintaining the sophisticated styling of BMW’s Sports Activity Coupe platform.
Constructed from premium prepreg (dry) carbon fiber, each diffuser is manufactured to deliver exceptional strength, lightweight construction, and consistent weave quality. Its sculpted design enhances the rear profile of the vehicle while complementing both factory and aftermarket exterior upgrades.
Finished with a high-gloss UV-resistant clear coat, the SQ-Aero Rear Diffuser is designed to maintain the depth and appearance of the carbon fiber while helping protect against fading, discoloration, and environmental exposure. The result is a durable finish that continues to look exceptional through daily driving and long-term ownership.
Designed specifically for the BMW G02 X4 LCI, the diffuser utilizes factory mounting locations wherever possible to provide precise fitment and seamless integration with the original rear bumper design.
Available with or without an integrated center brake light, owners can choose the configuration that best matches their build and styling preferences.
