SooQoo BMW G42 M240i Rear Side Diffusers In Gloss Carbon Fibre

The SooQoo rear side diffusers for the BMW G42 2 Series Coupe are designed to refine the lower rear profile with a clean, OEM+ inspired carbon finish. Developed specifically for M Sport models, these gloss carbon extensions integrate seamlessly with the factory rear bumper, adding subtle visual depth and a more purposeful stance without disrupting the original design language.

Constructed from prepreg (dry) carbon fibre, these diffusers offer a lightweight yet rigid structure with a precise weave pattern and refined finish. A high-gloss UV-stable lacquer coating provides 3–5 years of resistance against yellowing and environmental degradation, ensuring the carbon maintains its clarity and premium appearance over time. The result is a clean, consistent gloss finish that complements other carbon exterior elements.

Engineered to use original factory mounting positions wherever possible, installation is straightforward and secure, delivering accurate alignment and a factory-quality fit. Supplied fully tested for fitment, these rear side diffusers are designed to enhance the side and rear transition of the G42, creating a sharper, more cohesive lower profile.

This is a subtle yet effective styling upgrade for owners looking to elevate the exterior of their BMW G42 with genuine carbon fibre detailing and long-term durability.
