Priced per Pair!
The
Girodisc system is a direct replacement for the OE disc on all 997 Turbos, both
PCCB and non-PCCB equipped vehicles.
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.
Once the
Girodisc system is in place, simply replace the cast iron rotor when needed.
