Paragon Replacement Rotors for BMW M3 (G80) / M4 (G82/G83) – Rear Pair

Application: 2021+ BMW M3 (G80) / M4 (G82/G83)
Part Number: PRK.148.370.240.22100.08.01.R

These rotor rings (friction rings) are direct replacement for Paragon Performance 2-piece Rotors. Sold in pairs. Comes with new rotor attachment hardware kits (enough for 2 rotors) and assembly instructions for a complete rebuild.

Paragon Performance Rotor Ring offers superior braking and cooling efficiency optimised for track and race applications. It features directional ventilation vanes to create suction, turbulence, and guides cool air through the rotor for improved heat dissipation and increased resistance to cracking under harsh track conditions.

Made of CM-250 special formulated high carbon alloy cast iron, it allows for an optimal bite, thermal characteristics, high-temperature strength and durability. Rotor rings are heat treated to release stress in the rotor to avoid deformation and vibration, then turned by state-of-the-art CBN surface machining to ensure better break-in with new brake pads.

The floating 2-piece design allows thermal expansion of the rotor while minimising deformation and ensuring the rotor is self-centred with the pads. A slotted rotor improves braking consistency by maintaining a clean contact surface and dissipates heat generated and gases released when the pads come into contact with the rotors. Vibration is reduced as the rotor lateral run-out is kept within 0.03mm and well-balanced: variations are kept within 2 grams. Weighing less than most O.E. rotors while maintaining proper thermal capacity, our rotors improve overall handling by saving unsprung mass.
