RW Carbon G29 Z4 Carbon Fiber Side Skirts & Diffuser
1st Sep 2026
Give your BMW G29 Z4 a more aggressive, performance-focused exterior with the RW Carbon SQ Style Carbon Fiber Side Skirts and Rear Diffuser. Designed to work with the factory body lines of the Z4, these two carbon fiber upgrades add sharper definition to the vehicle's side profile and rear end while maintaining a cohesive, premium appearance.
Both components are constructed from 100% dry carbon fiber, providing a lightweight solution with a high-end carbon weave and motorsport-inspired appearance. Finished with a UV-resistant high-gloss clear coat, the components are designed to maintain their deep gloss while helping protect the carbon fiber from UV exposure and environmental elements.

SQ Style Carbon Fiber Side Skirts
The RW Carbon SQ Style Side Skirts extend along the lower sides of the G29 Z4 to create a more defined and aggressive profile. The SQ Style design complements the factory body lines while giving the vehicle a lower, more performance-oriented appearance.
Constructed from 100% dry carbon fiber, the side skirts combine lightweight construction with a consistent carbon weave and premium finish. The UV-resistant high-gloss clear coat adds depth to the visible carbon fiber while helping protect the surface from long-term UV exposure.
The result is a subtle but noticeable exterior enhancement that works equally well on a street-driven Z4, performance build, or show car.

Like the side skirts, the diffuser is manufactured from 100% dry carbon fiber and features a premium, uniform weave. A UV-resistant high-gloss clear coat provides a deep finish while helping protect the carbon surface against UV exposure and environmental elements.

Premium Dry Carbon Construction
Both RW Carbon components are manufactured from 100% dry carbon fiber. This construction provides the distinctive appearance associated with high-end performance components while keeping the parts lightweight.
The visible carbon weave is protected by a UV-resistant high-gloss clear coat, creating a deep, glossy finish that highlights the carbon fiber pattern and provides additional protection against environmental exposure.
Using matching materials and finishes across the side skirts and rear diffuser also allows the two components to function as a coordinated exterior styling package.
A More Complete G29 Z4 Exterior
The side skirts and rear diffuser address two different areas of the Z4's exterior while sharing the same SQ Style design language. The side skirts add definition along the lower body, while the rear diffuser gives the back of the vehicle a more aggressive appearance.
Together, they create a more cohesive performance-inspired look without requiring extensive changes to the vehicle's exterior.
These components are well suited to owners building a performance-oriented street car, show car, or custom Z4 project and looking to incorporate genuine dry carbon fiber into the exterior design.
