Show original supplier description
The Maxton Design Street Pro Rear Diffuser is engineered to enhance the aesthetic and aerodynamic profile of the Audi S3 Sedan 8Y, specifically for models from 2020 to 2024. Constructed from a durable 10mm ABS plastic plate, this diffuser is built to withstand the rigors of automotive use. Its material composition offers increased resilience to impacts and scratches, while also being corrosion-invulnerable due to the absence of metal elements. This rear diffuser boasts a fresh design with a neat edge finish, providing a subtle yet impactful visual upgrade. The product is available in two finish options: a clean 10mm-thick matte black, or a 10mm-thick matte black with a distinctive red core, offering a personalized look. Street Pro elements are characterized by their high durability and a no-need-for-painting application, though a primer layer is recommended if you choose to paint it. The ABS material used is specifically chosen for its sturdiness and elasticity, commonly found in factory bumpers and other car bodywork elements. Components made from this ABS have received TUV certification and TUV MATERIALGUTACHTEN certification, attesting to their quality and adherence to industry standards. Each part undergoes manual processing and finishing details, followed by strict quality checks before shipping to ensure minimal suboptimal items reach distribution. The set includes the Street Pro Central Rear Diffuser and a mounting kit, with PDF instructions and an assembly video available for installation.
