Thanks for the comments guys! Those are the center caps that accompany my wheels. Wheels are the MS-01's from the Mazdaspeed Accessory Catalog, they're actually for the RX-8, but fit well with 225/40/R18 rolled rear fenders and the drop I've got, which is fairly aggressive.
oh wow ok thanks for the info man.
Those rims look incredible and they should if they're from the MS catalog. They must have been mucho $$$!
Your car is very tasteful. I like the blue calipers matched with the blue emblems. I even like where you put the X-formers logo hahah (I'm an x-formers fan too!).
