Girodisc Advantages Girodisc brake kits are seen at every track weekend on very exotic and extreme track cars. What made Girodisc owners leave their OEM rotors and upgrade to a 2 piece Girodisc kit? Less Rotating Mass via two-piece design Grade 12 floating hardware to allow the rotor to grow when heated Curved vane design creates a cooler rotor Significant cost reduction compared to OEM Girodisc Floating Rotor Rings Quality hi-carbon cast iron is the foundation of every Girodisc brake rotor. Every rotor ring is made carefully in house at the Girodisc factory in Washington state. The Girodisc rotor utilizes a curved vane design that was originally developed in racing to act as a centrifugal air pump to force cooling air from the center of the rotor ring to the outside. This principle is similar to what is know as a squirrel cage fan design. By having impellers (vanes) between the two rotor faces, the air is moved radially, from the center outward, changing the direction of the airflow and increasing velocity. This design is mechanically strong, reliable, and very effective. Girodisc Rotor Ring Hardware The Girodisc rotor ring and light-weight aluminum hat have a floating mount system, which utilizes 8 or 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for long-lasting corrosion resistance. These drive pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The drive 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. Girodisc Rotor Ring Replacement Once the Girodisc system is in place, simply replace the cast iron rotor when needed. Your Girodisc replacement rotor rings come complete with two new rotor rings and all required floating rotor hardware. This is a very simple task that is quite fun. The aluminum rotor hat usually does not ever need replacement unless bent or damaged. If you damaged has reached your Girodisc hat, you likely have more than a few other things to replace also. The hat is rugged and overly strong.

Girodisc Ford S197 Mustang GT500 ('13-14) Rear Rotors These Girodisc 2-piece floating rear rotors are a direct replacement for the 2013–2014 Ford Mustang GT500 with the 5.8L engine and 350mm rear rotors. Designed for high-performance driving and track use, this upgrade offers superior cooling efficiency, reduced weight, and improved durability over factory components. Each assembly features a thicker 22mm rotor ring compared to the factory 19mm setup, providing enhanced heat capacity without requiring any modifications. The fully floating design reduces unsprung and rotational mass, improving suspension response and braking consistency under heavy use. Race-Inspired Design and Materials Each rotor ring is machined from Girodisc’s proprietary high-carbon iron alloy, engineered for superior thermal stability and resistance to cracking under repeated heat cycles. The 48 curved directional vanes function as internal air pumps, drawing cooling air through the center to effectively dissipate heat during braking. The hat is precision-machined from 6061-T6 aluminum and finished with a black anodized coating for corrosion protection and weight reduction. The floating system employs cadmium-plated steel drive pins, Belleville washers, and spring clips to ensure quiet operation and proper axial/radial float—ideal for both street and track use.
