The Girodisc system is a direct replacement for the OE disc. 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. Girodisc front rotors are approx 29.3lbs vs. 33.3lbs 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.
rotor and hat have a floating mount system, which utilizes 12 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.
