Paragon 2-piece Rotors Rear Pair 345mm x 24mm (13.58″ x 0.94″)

Paragon 2-piece Rotors (Rear Pair) – BMW F30/F31/F32/F33/F34/F36 with M Performance / M Sport brakes

Paragon Performance 2-piece Rotor offers superior braking and cooling efficiency optimized 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 condition.

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.

Vibration is reduced as the rotor lateral run-out is kept within 0.03mm and well-balanced: variations are kept within 2 grams. All rotors went through rigorous quality control procedures and inspections to ensure the rotors are fit for their purposes. A slotted rotor improves braking consistency by maintaining a clean contact surface and dissipate heat generated and gases released when the pads come into contact with the rotors. Slotted rotors have a superior advantage over blank rotors in wet or raining conditions by preventing water films to form between the brake pad and rotor surface. Weighing less than most O.E. rotors while maintaining proper thermal capacity, our 2-piece rotors improves overall handling by saving unsprung mass.

Aluminum hats are CNC machined from lightweight 6061-T6 aerospace grade aluminum for high strength and durability under extreme conditions, then anodized to increase resistance to wear and corrosion. Mil-spec hard anodizing will not discolor under extreme heat, while black anodizing is more prone to discoloring under heat (> 392F / 200C). Hard anodized surface is harder, thicker, and more wear and scratch resistant. Hard anodized surface will last longer than black anodized surface, and is highly recommended for track / race applications.
