Do the GiroDisc Z07 Rear Iron Rotor Conversion rotors keep the parking brake working?

Yes. GiroDisc states that the GiroDisc Z07 Rear Iron Rotor Conversion bolts directly to the C7 and works with the factory calipers and parking brake without issue. No machining, spacers or brackets are needed, so the rear brake system keeps its original layout.

Which C7 Corvettes is this rear conversion meant for?

It is meant for C7 Corvettes built with the Z07 package, which brought carbon ceramic brakes from the factory. Owners of those cars who want iron rotors for track work can fit this set in place of the ceramic rear discs without changing the calipers.

What happens when the rear iron rings on a C7 wear out?

Only the rings are replaced. GiroDisc sells the matching rear rings as part number D2-145, supplied in pairs with fresh mounting hardware, and the existing aluminum hats are reused. Replace them at the minimum thickness marked on the hat and ring edge, or sooner if a crack reaches the edge.

How does the rear rotor stay cool under repeated hard stops?

The ring uses curved internal vanes that work like a centrifugal pump, pulling air from the hub and forcing it out through the disc. The slotted face also keeps the friction surface clean and prevents a film of water from forming in wet conditions.

Does each rear rotor have to go on a specific side of the C7?

Yes. GiroDisc rotors are left and right handed because of the curved vane direction, and each assembly is labeled for its position. Fit each one to the side shown on its label so the vanes pump air outward as designed.

GiroDisc Z07 Rear Iron Rotor Conversion for C7 Chevrolet Corvette

GiroDisc’s Z07 Rear Iron Rotor Conversion lets a C7 Corvette ordered with that package retire its carbon ceramic rear discs in favor of two-piece iron rotors that bolt straight on. GiroDisc confirms no modifications are needed and that the factory calipers and parking brake work without issue. The ring is cast from GiroDisc’s own iron in the USA and floats on a 6061-T6 aluminum hat through 12 drive pins, so later service is a ring swap rather than a whole rotor. For a Z07 car that sees regular track sessions, it pairs naturally with the matching front conversion.

Bolt-On and Go

Installation follows the factory rotor procedure: the ceramic disc comes off, the GiroDisc assembly goes on, and the original caliper and parking brake return to their places. The cap screws that hold the drive pins are set no tighter than 60 in-lb, or 7 Nm, and can look loose by design. Anti-noise spring washers keep the floating ring quiet when cold while allowing it to grow with heat.

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.
