The 2009 models have the triangles. The previous generations have the solid piece. This is for both Gen and Rep. I think they didn't make the triangle one into the non day-date rep is that it required 43mm while the non day-date uses the 41mm case. Or they are just using all their inventory of solid rotors first before converting to the newer rotors. I saw the non day-date at the dealer and for the 41mm Carrera Racing, it has the newer rotors.
