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. The Girodisc front rotors are approx 17lbs vs. 25lbs 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.
