Are there warnings regarding counterfeit Sparco seat failures in the Mazda RX-7 FD?

There are serious safety warnings regarding the use of cheap, replica seats in general. If you are ever involved in an accident, a poorly constructed replica seat can fail, which compromises your driving position and renders your seatbelts unable to do their job ⁶. Critical safety equipment like seats, harnesses, and brakes should always be sourced from reputable manufacturers capable of achieving proper safety certifications ⁶.

As a known example of poor construction in replicas, some RZ-style replica seats (such as those from Angry Panda Factory) were marketed as carbon fiber but were actually just a cosmetic carbon overlay on top of standard fiberglass ⁶.

When shopping for seats for your FD, also keep in mind that the cabin is exceptionally tight. Genuine RX-7 Spirit R or RZ seats are specially contoured to fit this space, whereas many aftermarket or replica seats are too wide and will rub against the door panels ⁶.
