Product Details:

Upgrade the factory brakes or replace worn out rotors with premium GiroDisc brake rotors. Perfect for track use and a cost effective premium brake replacement solution vs PCCB.                                                                  
 
The central hat section of each rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from 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.

Once the GiroDisc system is in place, simply replace the cast iron rotor when needed - contact us for replacements.

FEATURES:

  • Fits all Porsche 997.2 GT3 / GT3 RS vehicles (2009-2011)

IMPORTANT NOTE  

When converting from carbon ceramic brakes to GiroDisc iron rotors we STRONGLY recommend replacing all four rotors in order to maintain the factory brake bias and controlled braking in all driving conditions.
