Girodisc Rear 2pc Floating Rotors for Alfa Romeo Giulia Quadrifoglio

The Girodisc system is a direct replacement for the OE disc however a different brake pad with an annulus (pad swept area) of 66mm or less must be used.  This is done to keep the rotor weight at a reasonable level.  If we manufactured a rotor with the same annulus as the OEM CCM rotors they would be far too heavy.

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 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 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.

Sold/priced in pairs.

This is a very aggressive track Rotor and pad meant for the track. 

We have done multiple of these conversions for customers. Customers are completely satisfied with how these pads and rotors withstand on the track and they are much cheaper than the carbon ceramic rotor counter part. This aggressive track set up will assure you can get to the front!
