This diffuser is engineered using state-of-the-art analysis software to maximize downforce generation while minimizing drag, leading to improved aerodynamic efficiency and increased tire grip at speed. Constructed from 5052-H32 sheet aluminum, the diffuser is CNC laser cut and CNC press brake bent for precision. It features a durable Powder-coated Low Gloss Textured Black finish and includes stainless steel hardware for a lasting installation. The design process utilized in-house scan data, resulting in a product with a near OEM fit and finish. The non-aggressive strake design offers a subtle yet clean aesthetic enhancement to the rear of the vehicle. Installation is straightforward with a simple, non-invasive, bolt-on design. This package includes the Rear Diffuser, Rear Diffuser Brackets, and a complete Hardware Kit.
