Porsche Upgraded Brake Rotors For Porsche 981 Boxster (2013-2016), 981 Cayman (2013-2016) Models.

Features:

• Premium U.S. Aluminum Hat: The central hat section of the rotor is constructed from strictly U.S.-sourced 6061-T6 aircraft-specification aluminum.

  
  

• Proprietary U.S. Cast Iron Disc: The brake disc is made from proprietary cast iron, poured and machined entirely in-house in the USA.

  
  

• Enhanced Cooling Design: Features a curved vane design, developed in racing, that acts as a centrifugal pump to force cooling air through the disc.

  
  

• Floating Mount System: Utilizes a floating mount system between the rotor and hat.

  
  

• High-Strength Drive Pins: Employs 10 high-strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for corrosion resistance.

  
  

• Load-Bearing Pins: These drive pins handle the load from braking forces while allowing axial and radial movement between the hat and disc.
• Secure Fastening: The pins are secured with class 12.9 cap screws and hardened washers.

  
  

• Anti-Noise Spring Washers: Incorporates anti-noise spring washers on the rotor side of the pins to prevent cold-start rattling and noise associated with floating rotors, while still allowing for thermal expansion.

  
  

• Self-Centering Rotor: The floating design enables the rotor to self-center between the brake pads.

  
  

• Replaceable Discs: Once the Girodisc system is installed, only the cast iron rotor needs to be replaced when it wears out.
