The Verus Engineering rear diffuser combines function, form, and science to deliver unparalleled fit, performance, and style to your Fiesta ST.

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; specifically with an aggressive strake design to give that aggressive and track-ready look.
