Paragon Replacement Rotors for BMW M3 (G80) / M4 (G82/G83) - Front Pair

This is a front pair of Paragon Performance rotor rings (friction rings) for rebuilding Paragon 2-piece rotors on the BMW M3 (G80) and M4 (G82/G83). Each ring is made from CM-250 high carbon alloy cast iron, heat treated to relieve stress and CBN turned for a better break-in with new pads. Paragon says the directional ventilation vanes help the rings run up to 30% cooler than OE rotors, with lateral run-out held within 0.03mm and balance within 2 grams. Each pair is supplied with fresh rotor attachment hardware kits, enough for two rotors, along with assembly instructions so the 2-piece rotor can be fully rebuilt.
