Description

The RW Carbon Hamann Style Carbon Fiber Diffuser is crafted to enhance the appearance of your 2008-2011 BMW E90 M3 Sedan. Constructed from genuine 1x1 plain weave carbon fiber, this diffuser is finished with a high-gloss clear coat that not only provides a striking shine but also protects the material from sun damage and road debris. The consistent 1x1 carbon fiber weave ensures it will seamlessly match other RW Carbon exterior parts for your E90 M3. Professional installation is recommended for this rear diffuser. It is designed to mount using self-tapping screws, 3M tape, and will reuse some of the original OEM hardware. RW Carbon emphasizes quality control, meticulously inspecting each piece before it ships from their Southern California location to ensure a defect-free product with superior fitment and construction. This commitment aims to prevent common issues like scratches or poor carbon fiber layering that can occur with parts shipped directly from overseas. Fitment is specifically for the 2008-2011 BMW E90 M3 Sedan. The part number for this Hamann style carbon fiber rear diffuser is bmwe9xm333. It is made to complement the aggressive styling of the M3 model.
