Blank front + rear discs with ceramic pads, that fit Rx8 models with NORMAL suspension, which means they have smaller calipers.
One sure way to determine which rotor you need is to simply measure it. Sport should be about 12.72 inches and the non sport would be 11.93 inches. The next and probably easiest way is if you have manual 6 speed transmission, then you would have the sport suspension. Automatic transmission users will probably have to check if their sway bar has a yellow or red mark. You can check for the mark on the sway bar which is just behind the passenger side tire, you can see it by turning the wheel all the way to the right. If it is yellow then it is a sport.
