Thanks to Ian for the tip: These are from Rays Wheels, a Japanese wheel site. Ã‚Â They’re called the 57Break and look just like mountain bike disc brake rotors. Ã‚Â Sweeeeeet…. Ã‚Â Now if only I still had my Integra GSR! Ã‚Â They come in Gold, too (the black center part is a dark gold color, not the “rotor”).
