These bad beasts came on the Miata. Trying to figure out the exact model number so I can google how much they weigh.

My best guess is that they’re Motegi Racing SX7's, weighing in at 20.5 pounds a piece (17x7), but google shows a lot of them are 2 tone. Perhaps these have been dipped to look charcoal? Any other leads would be greatly appreciated!
