A2-324 Girodisc 2pc Rear Brake Rotors (C5-C6 Corvette Z51) FITS: CHEVROLET CORVETTE C6 WITH Z51 PACKAGE (2005-2013) is an Authorized dealer for GiroDisc products and we are one of the largest stocking dealers in the country. We ship most products same or next business day to ensure we meet your delivery deadline. The GiroDisc system is an upgrade to a 2-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake disc. The 2-piece floating disc will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Giro Disc rotors are lighter than OEM pieces. The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC performance brake pads, and RF-1 brake fluid (also available from Discovery Parts), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron which is constructed in the USA and is made to the same specification with the same material used by professional racing organizations. The rotors curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc. The rotor and hat mount together through a floating mount system which utilizes 8-10 high strength alloy steel drive pins manufactured by GiroDisc in the USA to our own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat.

C8 Corvette Z06 Girodisc A1-320 Front Rotor Conversion (for Z07 CCB) Upgrade your C8 Z06’s braking system with the Girodisc A1-320 Front Rotor Conversion—designed specifically for Z07-equipped cars with carbon ceramic brakes. This 2-piece rotor kit bolts right up to the OEM calipers and replaces the factory carbon ceramics with high-performance iron rotors for improved consistency and cost-effectiveness on the track. Direct Fitment for Z07 Carbon Ceramic Brake Cars Fitment: Chevrolet Corvette C8 Z06 with factory Z07 CCB rotors This Girodisc system is engineered as a direct swap for the factory carbon ceramic front rotors on Z07-package C8 Z06 Corvettes. It retains the OEM calipers but uses a different pad shape (D1405), which is the same shape found on non-Z07 C8 Z06 models. The rotor rings are crafted from Girodisc’s proprietary high-carbon steel alloy, offering outstanding thermal stability and longevity. With 72 curved internal vanes, these rotors act as centrifugal air pumps, pulling in cool air through the hub to fight brake fade during aggressive use. The aluminum rotor hats are CNC-machined from 6061-T6 and anodized black for long-term corrosion resistance. The floating rotor design uses cadmium-plated drive pins, spring clips, and washers to allow axial float—ensuring race-ready performance while remaining quiet enough for the street. When the rotors reach minimum thickness (34mm) or if a crack extends to the edge, simply replace the rings (D1-320) and reuse the hats—keeping running costs low over time. Sold and priced per pair. Girodisc A1-320 Rotor Conversion Features: Direct replacement for Z07 carbon ceramic front rotors High-carbon alloy rotor rings resist cracking and heat cycling Curved vane design optimizes airflow for superior cooling 6061-T6 aluminum hats are lightweight and anodized for durability Floating two-piece construction reduces weight and vibration Compatible with D1405 pad shape used on standard C8 Z06 Girodisc A1-320 Rotor FAQs: Is this rotor kit track-proven? Yes, it has been tested under aggressive racing conditions and proven to hold up against repeated heat cycles and heavy use. Is professional installation required? While it’s not mandatory, we strongly recommend professional installation for optimal safety and performance. Will this fit my non-Z07 C8 Z06? No, this kit is specifically designed for Z06 models equipped with the factory Z07 carbon ceramic brakes. It uses a different pad shape and rotor size. Can I return this if it doesn’t fit? Yes, we accept returns on unused items in original packaging. Contact us for assistance if you're unsure of compatibility. Whether you're prepping your Z06 for heavy track use or want a more economical alternative to carbon ceramics, the Girodisc A1-320 rotor conversion delivers the perfect combination of durability, performance, and value.

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!

CALPIER REBUILD KIT FOR ALFA GUILIA CCM FRONT 28mm/32mm/38mm GiroDisc CCRK1-209 front caliper rebuild kit for Alfa Guilia CCM front caliper with 28mm/32mm/38mm seals. Track days can be especially hard on the piston seals and dust boots in your brake calipers. Heat, in particular, will do a number on them. (Titanium heat shields behind your pads can help with that.) This kit is put together from the highest-quality components to rebuild a brake caliper back to like-new condition. One kit is required per caliper (we suggest doing them both as long as you're doing it). Once you rebuild them, get the Ti heat shields as well and lengthen the interval between rebuilds. The shields and seals are available as a kit for convenience (and a bit of savings). We only source superior quality brake components (brakes for track use are serious business); some kits don't take it as seriously. Any questions give us a call, we're happy to help!
