Paragon 2-piece Rotors Rear Pair 350mm x 24mm (13.78" x 0.94") - BMW M3 (E90/E92/E93) / 1M Coupe (E82)

Paragon 2-piece Rotors (Rear Pair) for BMW M3 (E90/E92/E93) / 1M Coupe (E82)

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.

Center hats are CNC machined from steel for high strength and durability under extreme conditions, then anodized to increase resistance to wear and corrosion. Allow the use of OEM e-brake.

• Direct bolt-on without any modifications and designed to work flawlessly with OEM ABS and brake system while maintaining factory brake bias. Compatible with OEM brake pads or aftermarket pads with the same pad depth (D)

• Directional ventilation vanes for optimal cooling performance, runs up to 30% cooler than O.E. rotors and increase cooling efficiency by up to 30%

• 2-piece design

• Minimizing brake fade & judder during extended sessions

• Rotor to hat mounting system: Fixed hat, non-floating (10 bolt)

• Weighs 21.5 lbs per rotor
