The Verus Engineering Aggressive Rear Diffuser is engineered to significantly improve the aerodynamic performance of the 2015-2021 Subaru WRX/STI. This enhancement contributes to improved overall aerodynamic efficiency and increased tire grip at higher speeds. Constructed from robust 0.063-inch thick 5052-H32 sheet aluminum, the diffuser is built for durability and longevity. It features a CNC laser-cut and CNC press brake bent design for precise fitment, complemented by stainless steel hardware throughout. The exterior is finished with a powder-coated low gloss textured black, providing an aggressive aesthetic that complements the vehicle's styling. The package includes the rear diffuser, necessary brackets, and a comprehensive hardware kit to ensure a seamless installation process. The product is Made in the U.S.A. It aims to create a well-proportioned aerodynamic balance for the WRX by generating a low-pressure zone in the rear, working in conjunction with front splitters. This upgrade is beneficial for both daily drivers seeking better fuel economy and track enthusiasts aiming for improved performance.
