Girodisc Brake Rotors

U.S. sourced 6061-T6 aircraft aluminum center hat.  Proprietary cast iron disc poured and machined in the USA. Rotor mount design allows axial and radial movement to keep rotor centered. Rotor rings are a curved vane design that optimizes cooling. Hardware and discs are cadmium plated for lasting corrosion resistance. Two piece high performance brake rotors by Girodisc.


Racing technology designed and manufactured in USA

The Girodisc 2 piece rotor system is a direct replacement for the OEM brake disc and unless noted no additional modifications are necessary. The disc will bolt directly to the car and work perfectly with OEM calipers. Center hats are made from U.S. sourced 6061-T6 aircraft specification aluminum. The discs are made from Girodisc proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The discs use a curved vane design developed in racing that acts as a centrifugal pump to efficiently move cooling air.

High performance 2-piece floating brake rotors

The rotor and hat are a floating mount design which uses high strength alloy steel drive pins secured by grade 12 cap screws and hardened washers. The floating system allows both axial and radial float to keep the rotor self-centered under high heat conditions. Spring washers are also used to reduce rattle under cold or light use operation. Hardware and discs are cadmium plated for long lasting corrosion resistance.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.

Girodisc rotors are sold/priced per pair.
