    Girodisc Rear 350mm 2-piece Rotor for Porsche 987 with PCCB's

    The Girodisc system is a direct replacement for the OE disc on all 987 Caymans/Boxsters equipped with PCCB rotors from the factory.

    The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

    The rotor and hat have a floating mount system, which utilizes 8 or 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by grade 12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.

    Fits the following models:
    - All Boxster, Boxster S, or Boxster GTS models WITH Ceramic Brakes (PCCB) 2005-2016
    - All Boxster Spyder models WITH Ceramic Brakes (PCCB) 2011-2012
    - All Cayman, Cayman S, Cayman R, or Cayman GTS models WITH Ceramic Brakes (PCCB) 2006-2016

    Dimensions: 350 x 28 mm. 2-Piece design. Comes with the left and right front rotor. Made by Girodisc. Intended for off road use only. Professional installation required. Racing brake discs need to be regularly inspected by certified mechanics.
