Decrease lift and drag on your mk3 Focus RS with a simple bolt-on diffuser. Hatchbacks are notoriously bad with drag due to the dead water region behind the vehicle; our functional and aesthetically pleasing diffuser addresses this issue head-on. Our diffuser was designed to increase downforce and reduce this dead water region to reduce drag.
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.
This rear diffuser was designed for owners looking for function and form; specifically with a subtle strake design to tie into the vehicle's OEM body lines.
