The
Girodisc system is a direct replacement for the OE disc on all 996
GT2/GT3's. No modifications are necessary. The disc will bolt directly
to the car and work with OE calipers perfectly. By upgrading your brakes
with lightweight high performance replacements as opposed to a big
brake kit, your factory bias is maintained as well as your ABS
efficiency. The Girodisc front rotors are approx 21.0 lbs vs. 25.6 lbs
for the stock units. This reduction in rotational and unsprung weight
allows for quicker acceleration and suspension response.
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 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 class 12.9 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.
