Which C8 Corvettes take the GiroDisc Z51 Front Rotors for C8?

The GiroDisc Z51 Front Rotors for C8 are listed by GiroDisc for the Corvette Stingray with the Z51 Performance Package. The Z06 and E-Ray use their own GiroDisc parts, so confirm the Z51 package on the build sheet or window sticker before ordering.

Do the Z51 front calipers stay on the car?

Yes. GiroDisc describes this rotor as a direct replacement that bolts to the Corvette and works with the original calipers. Nothing in the hydraulic system changes, so the brake bias Chevrolet engineered and the efficiency of the ABS remain intact after the swap.

How is each Corvette front ring attached to its hat?

Ten high-strength alloy steel drive pins, made by GiroDisc in the USA and cadmium plated, hold each ring to its aluminum hat. The pins carry the braking load while letting the ring float, and class 12.9 cap screws with hardened washers keep them in place.

What part number renews the front iron later on?

The front ring pair for this rotor is GiroDisc D1-242. It arrives with new hardware and bolts to the existing aluminum hats, so a C8 owner who wears through the iron on track replaces only the rings rather than the complete assemblies.

Why are the C8 Z51 rotors slotted rather than drilled?

GiroDisc slots its discs to clean the friction surface and prevent a film of water forming in the wet. It does not recommend cross-drilled discs for performance driving, because the holes can become starting points for cracks under the heat of repeated hard stops.

GiroDisc Z51 Front Rotors for C8 Chevrolet Corvette

GiroDisc’s Z51 Front Rotors for C8 Chevrolet Corvette replace the factory front discs on a mid-engine Stingray ordered with the Z51 Performance Package, trading them for a two-piece floating assembly with an aluminum hat and a GiroDisc iron ring. They bolt on with the factory calipers, so the brake balance and ABS tuning stay as Chevrolet set them. For a C8 owner starting to run track days, it is the logical first brake upgrade: lighter discs and better airflow, with nothing on the caliper side to re-engineer.

Design and Performance

Each ring is cast from GiroDisc’s proprietary iron, poured in the USA and machined in Bellingham, Washington, and is joined to a 6061-T6 aluminum hat by ten cadmium-plated alloy steel drive pins. Curved vanes pump air from the hub outward, and anti-noise spring washers keep the floating ring quiet on cold mornings. Cutting rotating and unsprung weight is the point of the GiroDisc Z51 Front Rotors for C8, and the slotted face keeps the friction surface clean.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
