Description
The Verus Engineering Rear Diffuser for the Subaru WRX VB combines aerodynamic performance, functional design, and OEM-inspired fit and finish in a simple bolt-on package. Designed to reduce vehicle lift and drag while improving overall aerodynamic efficiency, this rear diffuser helps increase tire grip and vehicle stability at speed.
The diffuser was developed using advanced aerodynamic analysis and CFD to extract additional performance from the available space beneath the vehicle. Verus Engineering optimized the design to increase downforce while reducing drag, resulting in improved aerodynamic efficiency and performance on both the street and track.
During development, Verus Engineering utilized in-house scan data to achieve a near-OEM fit and finish. The result is a precision-engineered diffuser that integrates cleanly with the Subaru WRX VB while maintaining significant structural strength.
The Rear Diffuser is designed for enthusiasts looking for a combination of function and form. On track, the diffuser has helped increase both straight-line and cornering speeds while contributing to reduced lap times.

Aerodynamic Performance
The Verus Engineering Rear Diffuser is designed to decrease overall vehicle lift while reducing drag, improving the aerodynamic efficiency of the Subaru WRX VB.
The diffuser generates controlled vortices that help keep airflow attached to the diffuser surface, improving aerodynamic performance. By creating a low-pressure region beneath the rear of the vehicle, the diffuser contributes to increased rear downforce and improved stability at speed.
When paired with the Verus Engineering dive planes, the rear diffuser creates a more balanced aerodynamic package by adding rear aerodynamic load while the dive planes contribute additional front-end downforce. This combination forms the foundation of the Verus Engineering Ventus 1 aerodynamic package for the Subaru WRX VB.
For enthusiasts looking for additional aerodynamic performance and downforce beyond the Ventus 1 configuration, Verus Engineering also offers Ventus 2 and Ventus 3 aerodynamic packages.
Installation
The Verus Engineering Rear Diffuser uses a simple, non-invasive bolt-on mounting system and does not require permanent modifications to the Subaru WRX VB. The included brackets and hardware are designed to provide a secure installation while maintaining the diffuser's OEM-plus appearance.
