Mazda has just quietly published an updated version of their RX-7 heritage parts list. The program launched in December 2020 with about 90 parts total for both second-generation FC3S and third-generation FD3S models. With the latest update, there are now 30 items for the FC and 73 items for the FD.
To order them, you can go to a Mazda dealer in Japan. Unfortunately, there’s no definitive answer for whether these parts are coming to the US or not, but Mazda reassures us that it will continue to expand the list. For the full rundown, you can download the updated parts PDF file.
