Paragon 2-piece Brake Rotors (Front Pair) for Porsche 987 / 981 / 718 Boxster / Cayman with PCCB - Iron Rotor Conversion

Take your driving to the next level with our Performance OE Replacement Rotors. Designed specifically for your Porsche 987, 981, Boxster, and Cayman models, these 350mm x 34mm rotors provide enhanced performance and control. Upgrade to our iron conversion for even greater power and precision.

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. The floating 2-piece design allows thermal expansion of the rotor while minimizing deformation and ensuring the rotor is self-centered with the pads. 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 track conditions, then black hard coat/hard anodized to increase resistance to wear and corrosion. Mil-spec Type III anodized hats will not discolor under extreme heat, and are harder and more wear/scratch resistant. Unnecessary materials are taken out from the aluminum hats for maximum weight savings while maintaining proper structural integrity.
*Black hard coat and hard coat anodized hats are the same in terms of performance and durability.

  • 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%

  • Floating 2-piece design

  • Minimizing brake fade & judder during extended sessions

  • Weighs 21 lbs per rotor assembly
  • Rotor to hat mounting system: D-Bobbin (Long) - 10 bolt
  • Convert factory ceramic composite rotors to cast iron rotors. Superior track durability, reduce maintenance cost.
