Show original supplier description
The Maxton Design Street Pro Rear Diffuser is designed to enhance the aggressive styling of the BMW X1 M-Pack F48 models from 2015 to 2019. Crafted from a durable 10mm ABS plastic plate, this component offers increased resilience against impacts and scratches, ensuring long-lasting performance and aesthetics. The material used in its construction is known for its corrosion-invulnerability, as it contains no metal elements, and its resistance to harsh weather conditions, including extreme high and low temperatures. The ABS plastic is further protected with a UV-protective coating, preventing fading and degradation from sun exposure. The diffuser features a fresh design with a neat edge finish and comes ready for immediate installation without the need for painting, though a primer layer is recommended if painting is desired. This rear diffuser is TUV MATERIALGUTACHTEN certified, underscoring its quality and adherence to automotive industry standards. The ABS material is specifically chosen for its robustness and elasticity, commonly used in the manufacturing of factory bumpers and other car bodywork elements. Each part undergoes meticulous manual processing and finishing, followed by strict quality checks before shipping to eliminate suboptimal items. The complete set includes the Street Pro Central Rear Diffuser and a mounting kit. It is available in two finish options: a 10mm-thick matte black, or a 10mm-thick matte black with a red core, providing options to match your vehicle's aesthetic.
