These are Paragon Performance rotor rings (friction rings) measuring 343mm x 25mm with a 222mm P.C.D., listed as D50 and sold as a pair. Paragon lists them as a replacement for the Alcon DIV2175X543 ring. The rings are made from CM-250 high carbon alloy cast iron that is heat treated and CBN turned, and Paragon says the directional ventilation vanes help them run up to 30% cooler than OE rotors. It also quotes lateral run-out within 0.03mm and balance within 2 grams.
