C8 Corvette Z06 Girodisc A2-319 Rear Rotors (for OEM Steel & Z07 CCB) Fitment: Chevrolet Corvette C8 Z06 This Girodisc two-piece rotor set is a direct replacement for the rear rotors on the Chevrolet Corvette C8 Z06 with either the factory cast iron rotors or the Z07 carbon ceramic rotors1. Girodisc two-piece, fully floating rotor assemblies help shed unsprung weight and rotating mass from the front axle of the C8 Z06 with iron rotors, while being far more durable in track use than the fragile and very expensive Z07 carbon ceramic rotors. American Made With Specially Formulated Materials Girodisc rotor rings are machined from a proprietary casting made of high-carbon steel formulated to Girodisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 72 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The two-piece design means the reusable hat which can be attached to new rotor rings (part number D2-319) when the latter need to be replaced. All major components including the hats, rotor rings, and drive pins are manufactured in-house at the Girodisc facility in Bellingham, WA, from domestically-sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodized finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware. The minimum thickness at which we recommend replacing these rings is 32mm. We also recommend replacing them if a crack leads to the edge of the ring. Sold and priced per pair. 1 Note: when replacing factory Z07 carbon ceramic rotors with this Girodisc iron rotor kit, you will need to choose a rear brake pad shape for the factory iron-rotor C8 Z06. If you would like help choosing rear pads, give us a call at (888) 748-7223 any time!

As one of the largest stocking dealers in the country, we ship most Girodisc products the same or next business day to ensure we meet your delivery deadline. Fits Nissan GT-R (DBA) 2012+ w/ 390mm stock rotors The Girodisc system is a direct replacement for the OE disc, they will bolt directly to the car and work with OE calipers perfectly. The central hat section of the Girodisc rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc's 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 forcing cool air through the disc. The disc and hat have a floating mount system, which utilizes 12 high-strength alloy steel drive pins, manufactured in the US by Girodisc and cadmium plated for long-lasting corrosion resistance. These pins take the loads from braking while maintaining the axial and radial float between the hat and disc. They are secured by class 12.9 cap screws and hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise springs on the disc side, allowing the iron disc to expand as it heats up while eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the brake pads. Once the Girodisc system is in place, you simply replace the cast iron discs when needed. This reduces cost over time by allowing you to re-use the aluminum central hats. Sold/priced per pair

What made GiroDisc owners leave their OEM rotors and upgrade to a 2 piece GiroDisc kit? Less Rotating Mass via 2 piece design Lightweight 6061-T6 Aluminum Hat 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 Rotor Hat: The GiroDisc rear central is manufactured using aircraft grade 6061-T6 aluminum. Less weight creates a huge advantage in acceleration and braking. Anyone who has spent the money for a lightweight double disk clutch kit with aluminum flywheel knows the importance of rotating mass. Using a lightweight rotor kit allows the brakes to decelerate the vehicle not the rotor. GiroDisc Floating Rotor Ring: 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 very effective. Chances are your street cars heater blower motor and home furnace utilize GiroDisc Rotor Ring Hardware: The GiroDisc rotor ring and light-wight 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 our own specifications and cadmium plated for a 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 2 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 almost have quite a bunch of other things to replace also. The hat is rugged and overly strong.
