Description
The Group A Mazda RX7 FD3S Spec RE Pro Diffuser Vortex Generators are aerodynamic finlets for the Spec RE Pro rear diffuser on the Mazda RX-7 FD3S. These vortex generator fins mount within the diffuser channels to energize the boundary layer airflow, preventing premature separation inside the diffuser tunnel. By maintaining attached flow through the diffuser, these generators allow the diffuser to produce more consistent downforce at a broader range of speeds — improving rear stability during both entry and exit phases of corners.
Precision-matched to the FD3S Spec RE Pro diffuser geometry and manufactured from lightweight composite material.
