Designed specifically for the 2015-2021 Subaru WRX and STI with VA chassis, the IAG Rear Diffuser enhances the car’s rear-end appearance with a bold, race-inspired look. More than just a visual upgrade, this aerodynamic diffuser helps improve airflow at the rear of the vehicle, reducing drag and increasing downforce for greater stability. The IAG Rear Diffuser is the perfect addition for track applications or anyone looking to give their Subaru a more aggressive appearance.
Constructed from lightweight 5052 aluminum, the IAG Rear Diffuser delivers durability without adding excess weight to the Subaru VA chassis. Each piece is precision laser-cut for a perfect fit on the WRX and STI. It features a powder-coated gloss or matte black finish that enhances durability and protects against corrosion, while the included corrosion resistant black-oxide hardware blends into the diffuser’s surface for a seamless, streamlined look.
With an adjustable design, the IAG Rear Diffuser can accommodate various aftermarket exhaust setups. The outer sections below the mufflers can be raised or lowered independently from the main center section, allowing for a closer fit without affecting the main center section. Additionally, the center section itself is height-adjustable, ensuring a precise fit and optimal aerodynamic performance.
The IAG Rear Diffuser is both easy to assemble and install. The diffuser mounts directly to pre-existing factory mounting locations without the need for drilling. It includes all necessary hardware, and with some mechanical experience, installation can be completed in under 2 hours using basic hand tools.
