Show original supplier description
The Maxton Design side skirts diffusers are precision-engineered to provide a sharp, aggressive aesthetic to your Ford Focus ST or ST-Line Mk3 and Mk3 facelift hatchback or estate models. Manufactured using 3D laser scanning technology, these components ensure an accurate, direct-fit installation. Each diffuser is crafted from high-impact, scratch-resistant, and shock-absorbent ABS plastic, a material frequently used in original equipment manufacturing for its durability and longevity. Each set includes the necessary mounting kit and installation manual. The material is TUV (TUV MATERIALGUTACHTEN) certified, and the surface features a specialized UV protection coating to resist fading. This product is ready for installation out of the box and requires no additional preparation work. For the best results and structural integrity, professional installation by an auto body shop experienced in visual modifications is highly recommended. Compatibility is strictly limited to the Ford Focus ST and ST-Line Mk3 (2013-2014) and Mk3 facelift (2015-2018) hatchback and estate configurations.
