did you ever sort this out? I am trying to get some fr500 wheels as well and wondering if machining the rotor is all that is required to make these fit.
Not exactly, but I'm just going to purchase racestars. Racestar 92 is what I had on my svo foxbody and they will git these rotors. I am eventually going to just get wheels I like and machine the snout down on the hub.
