Just an update for those playing at home: the Mazdaspeed MS-01S and MS-01MAG rims have been discontinued by Rays/Mazdaspeed, and there's no stock left. So if you're after a set, secondhand will be your only option.
The only rims currently made for Mazdaspeed are the Enkei-made multispoke rims as found here:
