The Verus Engineering Rear Diffuser combines function, form, and science to deliver unparalleled fit, performance, and style to your Fiesta ST. Constructed from sheet aluminum and mounted to hardpoints on the chassis; the unit is strong and light; and very capable of increasing rear end grip on this chassis!

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.

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

The rear diffuser was designed for owners looking for function and form.

The goal of the diffuser is to improve grip and reduce drag. Hatchbacks are notoriously drag prone due to the overall body shape. A properly designed rear diffuser improves the wake region and thus improves drag on these style of cars. The other benefit is increased downforce at high speeds; which increases handling, improves safety, and increases corner speeds.

Pair the rear diffuser with our dive plane kit for a nice bump in downforce, no major change in drag, and an aerodynamically balanced package.
