Show original supplier description
The Maxton Design Rear Diffuser is engineered to enhance the visual appeal and aerodynamic performance of the Subaru Impreza WRX STI models from 2009 to 2011. Maxton Design utilizes 3D laser scanning technology to ensure perfect fitment for each specific make and model they design for. The product comes TUV certified for material quality and features a UV-protection coating, ensuring longevity and resistance to the elements. It is ready for installation, though painting may be required for textured versions, and professional installation by experienced auto body shops is highly recommended. This rear diffuser is specifically designed for the Subaru Impreza WRX STI version, model years 2009 through 2011. It's important to verify fitment with your specific vehicle configuration, as UroTuning does not list all vehicle fitments for this item.
