Description
The Group A Mazda RX7 FD3S Spec RE Street Diffuser is a rear underbody aerodynamic diffuser for the Mazda RX-7 FD3S (1992–2002), designed as the street-spec version of the Spec RE diffuser family. Unlike full race-spec diffusers that may have ground clearance challenges, the Spec RE Street Diffuser is proportioned for day-to-day street use — providing meaningful rear lift reduction without the aggressive channel depth that can cause clearance problems on urban roads. It’s a practical aero upgrade for street-driven FD3S builds.
Fiberglass construction, supplied raw for body prep and paint. Mounts beneath the FD3S rear bumper.
