Anyone who has looked at the brakes on the front of the C8 Corvette Z51 know right away the brakes could use some help. The stock rotors lack performance and also lack the looks a quality sports car like the Corvette deserves. Girodisc has fixed that issue with these 2PC rotors. They not only look great, they add key performance aspects. They reduce the rotational weight of the brake assembly and add slots which, removes gasses that generate between the pad and rotor under hard braking. These two key aspects greatly increase the cars braking performance.
Front Stock Rotor Weight = 24lbs
Front Giro Disc Rotor Weight = 21lbs.
Save 6lbs on the front axle with the full set replacement.
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 and parking brake without issue.
The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from 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.
