The Verus Engineering Rear Diffuser combines function, form, and science to deliver unparalleled fit, performance, and style to your GR Hatch.

Utilizing state-of-the-art analysis software during the R&D process, we were able to extract more performance for the given build volume; increasing downforce generated and drag reduced from the addition of the rear diffuser to the GR chassis.

During the design process; we utilized in-house scan data.  This results in a product that features a near OEM fit and finish.

The Rear Diffuser was designed for owners looking for function and form; specifically with a non-aggressive strake design to give a subtle and clean rear-end look to your hatchback

The Verus Engineering Ventus 1 package decreases the overall lift and reduces the drag of the VA WRX.  The components end up improving the aerodynamic efficiency of the vehicle as a result. The diffuser helped create vortices that keep flow attached to the diffuser surface. The diffuser creates a low-pressure zone in the rear while the splitter creates a low-pressure zone in the front. This equates to a well-proportioned aerodynamic balance for the WRX.

The Verus Engineering Ventus1 package helps your WRX get more from the tires at the track and also increase gas mileage on a daily driver. The rear diffuser in the Ventus 1 package is a great addition to both daily drivers and track addicts alike.
